Unresolved Disputed Charges and Lack of Customer Service Response

I am writing to express my extreme dissatisfaction regarding a matter that has caused me considerable frustration and inconvenience. I previously reported an unauthorised charge on my account and subsequently contacted your customer service team. I was assured that I would receive a follow-up call to address this issue; however, to date, no such communication has been received.

Furthermore, despite my attempts to resolve the matter, the identical amount in question has been debited from my account once again. This situation is highly concerning and raises questions as to whether there has been any mishandling or internal oversight.

For reference, the first case number is ***2, and the second case number is ***3. Despite raising these cases, there appears to be no intention or action taken towards resolving the issue. I insist on an immediate and thorough investigation and a full refund of the disputed amount.

I expect prompt communication and resolution of this matter without further delay.
