Bank problem

I need a few more details from you before I can draft a clear complaint. The notes only mention "bank problem" and "Fraud/Cheating" against "Abc," which is not enough to write a factual complaint. Could you please share: the name of the bank or branch involved, what product or service was involved (account, loan, card, transaction, etc.), what exactly happened and when (dates), any amounts involved, whether any transaction or deduction happened without your consent, and what steps you already took (complaint to bank, reference/complaint number, customer care calls, emails) and their response. Once you share these facts, I will write a clear, first-person complaint description for you covering what was agreed, what went wrong, your attempts to resolve it, and what you now demand from the bank.
