Unauthorized billing

I am writing to formally express my dissatisfaction regarding a double billing issue on my car tracking account. Upon reviewing my recent billing statement, I noticed that I have been charged twice for the same service period (November), which appears to be an error.

I have verified my payment records and can confirm that this duplicate charge was not authorized. This issue has caused unnecessary inconvenience and concern, and I expect accurate and transparent billing for the services provided.

I kindly request that this matter be investigated promptly and that the duplicate charge and banking fees be refunded as soon as possible.

If any additional information is required from my side to resolve this matter, please let me know. I would appreciate a prompt response and timely resolution.

Thank you for your attention to this matter. I look forward to your response.
