Finchoice Loan

Greetings, All My complaint is that there was money deposited into my accounts from finchoice. 2 separate SMS's notified on my account i then immediately notified the service provider via telephone and I was advised to deposit the money back of which I did because the money was mistakenly deposited into my account. Came month end there goes a debit order of R253 off my account from finchoice, I called in to query about it again then I was told to submit and affidavit of which but surprisingly I'm still being debited every month. I'm requesting that this being resolved ASAP as it is an inconvenient for me, I'm absolutely not happy with the service I get whenever I go to the brunches. The Case has been going on since last year.
