Pathetic Service

My policy was cancelled however i was still debited, prior to that i requested Capitec to switch my debit from Nedbank to Capitec as i was no longer using the account and it was done and the debit even went through from Capitec and after my plan was cancelled i requested for a refund of my premium which was done but paid into the wrong account(Nedbank)how can you debit me from Capitec but refunded to the old account that i switched,somebody phoned me and promised to look into the matter but till today, i got no feedback n no money, i want the money to be paid into the account you debited from and i wont rest until it is done.
