Formal Complaint and Request for Account Verification

I am writing to formally lodge a complaint and address a concerning matter regarding the unwarranted communications I have been receiving from your organization regarding an alleged outstanding amount on my account. I trust that this letter will bring clarity to the inaccuracies in your records and resolve the issue promptly.

In 2021, I initiated a request for a fiber installation with Supersonic and fulfilled all necessary payment obligations for the service. Regrettably, the installation was canceled due to a company policy prohibiting installations in flat buildings. Subsequently, I sought a refund, and only after escalating the matter to the ISP Ombudsman did I receive the reimbur*****t.

It has come to my attention that despite the cancellation and refund, I am now receiving calls and messages from Supersonic suggesting an outstanding balance. I want to emphasize that I have neither maintained any standing account with Supersonic nor utilized any services since the cancellation. This has caused significant stress and inconvenience.

I kindly request that you promptly investigate and rectify this situation by verifying my account status with Supersonic. I believe that Supersonic should have a comprehensive record of the refund and the circumstances surrounding the cancellation, given that it occurred less than five years ago. If there are records indicating otherwise, I request immediate clarification on the matter.

I hope we can resolve this issue amicably and promptly. However, should these unwarranted communications persist, I will have no choice but to escalate the matter once again to the ISP Ombudsman. I trust that it will not come to that, and we can work collaboratively to rectify this situation.
