Poor Feedback and Response

I have received bad service from Nedbank and their legal card division.Firstly,their number is never available and when you are transferred from the credit card division it prompts you to leave a message to which they never respond. I have been paying the Green Affinity credit card which I was taken to the legal division without my knowledge for the past year, I have been paying over and above the required amounts because I don't want to interact with them anymore but I cant get through to them to receive my balance and I have never been sent a statement on the amount I owe and my payments thus far yet I receive sms to instruct my payment. I want to physically see my payments, and my balance.It is that pure and simple.
