Personal loan

I app**** for personal loan at kyalami corner last month. And the agreement was my 1st instalment will be the 01/12/2017. To my surprising my capitec saving account was debited on the 25/11/2017 for R1081.00, then I phoned the collection department and came to an agreement of paying the balance on 01/12/2017. On the 30/12/2017 the full debit amount went off. I phoned again to query the debit order and the lady said they will reverse the 1081 and she will also cancel the arrangement of the balance, on the 01/12/2017 the balance went off, this is a bad service I ever came around and I didn't expert this from the no 1 good service bank in SA
