Attention: Store Manager

Dear Sir/Madam,

RE: COMPLAINT REGARDING INCORRECT TRADING HOURS DISPLAY AND DEMAND FOR COMPENSATION

I am writing to express my extreme dissatisfaction and to register a formal complaint in the strongest possible terms regarding the incorrect display of trading hours at your Costco Auburn NSW store.

My wife and I visited your Auburn store on 7th April 2023 at approximately 1:00 PM, only to find it closed, much to our shock and immense disappointment. Before leaving home, we not only checked your official website, but also called your store for confirmation that it was open. There was a recorded message which referred us back to your website, which indicated that the store was open.

Upon arriving at the Costco parking, we turned and noticed numerous other vehicles turning in with the expectation of shopping, but the carpark was locked. We all had to turn around and leave. 
The closure of the store, left us feeling extremely agitated, upset, and deceived.

We then made several attempts to contact your store by phone but received no response, only the same automated message, referring us to your website. Your website still displayed the store was open, which further heightened our sense of anger, disappointment, and agitation. 

We were let down by Costco, a company with whom we had entrusted our shopping needs and expected reliable and accurate information.

Our long journey to your store not only caused us to waste petrol and an increase in the wear and tear of our vehicle but also led to the squandering of our valuable time. This time could have been better spent on other activities, rather than being frustrated and upset due to the negligence of a multi-billion-dollar company like Costco.

Your failure to meet your legal obligation to correctly display your opening hours and your misleading actions have resulted in a severe breach of our trust. We feel intensely deceived and cheated, and this ordeal has left us questioning our loyalty to your brand.

Given the distress and inconvenience we have experienced, we demand appropriate compensation for the losses and emotional turmoil we have endured as a result of your negligence. We expect a prompt response to this letter, detailing the steps that you will take to rectify this situation and the compensation we expect to receive for the adverse effects of your actions.

Thank you for your attention to this matter, and we look forward to your prompt response.

Yours faithfully,
[Your Name]} 

{Letter 2:
I am writing to express my extreme dissatisfaction and to register a formal complaint in the strongest possible terms regarding your failure to incorrect display your opening and trading hours which showed that your Costco Auburn NSW store was open which in fact was closed and then the lack of an accessible contact email address on your website so that we could communicate with you, to lodge this complaint.

After returning home when we visited your Auburn store on 7th April 2023 at approximately 1:00 PM, only to find it closed, to our shock and enormous disappointment. Our frustration was further exacerbated by the fact that we were unable to locate a direct contact email address for your store on your website. This omission not only appears intentional, as though it is designed to frustrate customers and discourage them from lodging complaints or inquiries, but it also contradicts good customer service practices and may even be considered unlawful.

The incorrect trading hours display, combined with the difficulty in finding an appropriate contact email for addressing our concerns, has resulted in a significant waste of our time and money, as well as added frustration that only fuels our determination to ensure compliance with the Australian Consumer Law (ACL) legislation.

In light of these events, we are demanding appropriate compensation for the inconvenience, distress, and additional time loss caused as a result of your negligence and intentional obscurity of contact information.

We expect a prompt response to this letter, detailing the steps that you will take to rectify this situation and the compensation we will receive for the wasted time, effort, and resources that have resulted from your lack of transparency and inaccurate information.

Please ensure your response includes a direct and accessible email address and other contact information so that we can communicate further and seek the necessary redress without additional delays and frustration. Your lack of appropriate communication options demonstrates a disregard for customers’ needs, which serves only to amplify our dissatisfaction and sense of being misled by your company.

Yours faithfully,}

Combine the content of both letters (letter 1 and letter 2) into one new letter of complaint and label it ‘letter 3’;  the second letter was drafted after further frustration upon us because Costco does not have a contact email address on their website to communicate which made me waste even more numerous hours searching the web to try to find, an easier way for us, (electronic form of communication), that I could use to lodge my letter 1 complaint,  but I was not successful; Include also the reasons I have just stated above in the new letter of complaint and label it letter 3.
