Disgusted by the Capitec Bank

I have a PL account with capitec bank and they have not been deducting the same amount monthly. I have been told I am on arrears when the debit order has gone through from my account. I have moved my salary account from Capitec to Nedbank but its still the same issue. Been to the Fourways Branch in March to get assisted but I was told I need to contact the collections Department. Today I contacted the collections department but I was being transferred from one agent to the next. No one is willing to assist me. I am appalled by capitec customer service. This whole issue is affecting my credit record. I regret the day I went to Capitec for a PL. would appreciate if someone can assist me
