Summarize this article in one sentence.
If onsite staff are unwilling to help, unable to help, or if you are still dissatisfied, you may want to contact the larger business entity. As the entity responsible for the branding of the business, a corporate office may be much more responsive to consumer complaints. Do an internet search on the business and look for their corporate contact information. Send an email or a letter to the appropriate person. Make sure to be polite and clearly articulate the problem or issue. Call the corporate entity and ask for customer service or the customer complaint department. Be polite and clearly explain the problem. Say something like "Hello, I was a guest at your location in Boston's Back Bay. I was extremely disappointed with the service and cleanliness offered there. I feel taken advantage of." If you booked the hotel through a travel or booking website, you may be able to complain directly to that business. Be prepared to be put on hold for potentially long periods of time when contacting booking website customer service. Clearly articulate your complaint. Have your transaction number or receipt at hand. Be able to provide evidence, such as photographs, police reports, or the names of customer service representatives at the hotel. Be aware that hotel or travel booking websites are very often unresponsive to customer complaints. This owes to their high volume and slim margins on individual transactions. If the booking business is unable to resolve your complaint, your last recourse is to post a negative review about the hotel in question on their website. Depending on your complaint, you should consider contacting the relevant regulatory body. As government agencies that oversee businesses that offer public accommodations, they'll be able to deal with and issue appropriate sanctions. If you're complaining about a health and sanitation issue, contact the local health department. Consider contacting the state or province's division or department of hotels and restaurants. If your complaint is serious enough, the licensing agent may take action or launch an investigation into the hotel in question.
Contact the corporate entity, if one exists. Contact whoever you booked the hotel with. File a complaint with any relevant regulatory body.
