Poor customer service

I opened a cheque account n app**** for a loan . The money was debit to my old saving account instead for 2 mnths. Now they debit my account twice without my consent. I phoned the call centre today and wasnt even asked about making an arrangement. Poor poor service indeed. No refunding as im in arrear according to the consultant . This resulted in unpaid debits for other accounts. This is not on. Firstly it wasn't my fault that the incorrect account was debited and 2nd there has been a consultant that called me to make an arrangement but because I work in a call centre myself I dont havehave lunch breaks the same everyday hence I asked her to call me @6h30 in the afternoon which was alao jot done
