I used a template I found in this thread:
Upon reviewing my recent bank statements, I noticed discrepancies in the descriptors associated with transactions from your platform. It appears that some of the descriptors are inaccurate and do not align with my legitimate transactions. This has caused confusion and concern on my part.
I kindly request your prompt assistance in rectifying this matter and processing refunds for the transactions with false descriptors. To help facilitate this process, I have attached relevant screenshots and details of the transactions in question.
I understand that errors can occur, and I appreciate your attention to resolving this matter promptly.
