Problem: Article: When writing a letter of complaint, your best chance of success will come from directing the letter to the customer service department of the company. The customer service department is accustomed to dealing with complaints and your letter is likely to be processed efficiently and effectively. Try to find out the name of the customer service manager or director and address your letter to them personally. Begin your letter with Dear Mr, Mrs, Miss or Ms followed by their surname. If you cannot find the name of the customer service manager, simply write Dear Sir or Madam. You should be able to find the address of the customer service department on the company's website, on any of the company's promotional or advertising materials or product packaging or labels. The very first line of your letter should clearly address why you are writing the letter and what your exact complaint is. Give as many pertinent facts as possible, including the date, time and location where you made the purchase or received the service, along with any relevant serial or model numbers. The recipient of the letter should be able to identify the point of the letter in under five seconds, so avoid any long, rambling intros. You may provide further detail or explanation of the situation in the paragraph following your opening sentence, but the first line should draw attention to your complaint as succinctly as possible. For example, your opening sentence might read: "I am writing to complain about a faulty hair dryer that I purchased from your company on the 15th of July at your location on First Street, Exampletown." If you want a replacement, a refund, a repair, or some other form of compensation, state this clearly in your second paragraph. This will help to avoid receiving a form letter or other stock response, and give the recipient something to work with on their end. Try to be as constructive as possible in your comments, suggesting a way that you can move forward and continue your relationship with the company. If you demand a refund or some other form of compensation, while simultaneously informing them that you plan on taking your business elsewhere, they will have little incentive to try to resolve the problem If you would like the company to correct a broader problem, state that in your letter as well, but recognize that such a thing may take time. Do not threaten legal action in your first communication. It may be the solution you ultimately require, but send your complaint letter first and await a response. These may include receipts, guarantees, warranties, copies of checks you sent and, if appropriate, photos or videos. All documentation should be included with your letter. Make sure that you send copies of any documentation you wish to include, not the originals. That way, there's no chance of this key information being lost or mislaid, should you need to provide evidence to someone else. Also make sure to state in the body of the letter the exact materials you are including. For example: "Please find attached a copy of my original receipt, along with a copy of the hair dryer's guarantee and information regarding the serial number." It is helpful to provide an exact time period within which you would like the issue to be resolved. This will give you peace of mind and will help bring the issue to a speedy conclusion. Providing a time limit will also help to prevent the possibility of your letter becoming lost or forgotten about, which may lead to further awkwardness and resentment between you and the company. Just make sure that the time period you provide is reasonable. A week or two is usually sufficient, though this will vary depending on what your requests are. Thank the recipient for their assistance, and let them know how and when they can reach you to resolve the matter. This will make their job a lot easier, resulting in a more efficient outcome for you. Sign off the letter with Yours sincerely, if you know the name of the person you are writing to, or Yours faithfully if you referred to them as "Sir" or "Madam". Avoid informal closings such as "Best," or "Yours truly."
Summary: Address your letter to the customer service department. Quickly get to the point of your letter. State specifically what outcome or remedy will satisfy you. Attach copies of supporting documents. Give them a time limit to resolve the matter. Finish the letter respectfully.

In one sentence, describe what the following article is about: The underlying functionality of Prezi means that you do not have to think in linear slides as you would PowerPoint. You are free to move the frame around your presentation landscape however you feel is best. This means, however, that a Prezi that is not planned properly from the beginning can quickly become a jumbled mess with no sense of direction. Draw out an overarching design of the Prezi. Think of how the presentation would look if it was completely zoomed out. Some of the most successful Prezis have a structure that the path of frames will follow. Use the main points of your presentation as the anchors for the path your Prezi will take. Think of these main points as "focal" points; you will be focusing on these and using the surrounding landscape to build on them frame by frame. The path is how the presentation transitions from frame to frame. Instead of going in a linear motion, the path can be set in any order, and the "camera" will move around the presentation as it follow the path. When you are planning out your Prezi, think about how you will be moving the camera over your landscape. Because Prezi allows for full zooming and rotations, there is a temptation to change the perspective often during a presentation. This can lead to motion sickness in the viewer, and distracts from the content of the presentation. Try to layout out your landscape so that the camera moves in a relatively linear fashion, either horizontally or vertically. Avoid rotating as much as possible unless it significantly enhances the message Save the zoom in and out feature for transitions between large sections. Zooming too much can be disorienting and distracting. Use the special features of Prezi sparingly to emphasize their effect on the audience. Because you have an essentially limitless canvas, make your focal points big to begin with. Then, as you add more details, you can add smaller objects and use small amounts of zoom to focus on them.
Summary:
Sketch out your concept. Set the foundations with your main points. Think of your Prezi in terms of the "path". Keep your paths steady. Start big.
