I want my refund please from finchoice and their poor service

Here's a revised paragraph:

I'm writing to express extreme dissatisfaction with FinChoice's handling of my account. Despite multiple complaints and calls, issues with double debits and incorrect payments were never resolved. Agents, including Thembakazi, would often hang up or provide unsatisfactory responses. FinChoice incorrectly reported missed payments to credit bureaus. I asked African Bank to settle the account, but FinChoice's payment processing was inaccurate. I'm requesting a full refund for the excess payment and demand resolution to this matter. I expect FinChoice to take immediate action to correct the errors, provide a refund, and ensure my credit report is updated accurately.
