Account Verification Details

Just phoned your call centre because a company that owes me money keeps on telling me that my account details cannot be verified. Was asked 4 security questions and I answered honestly. I KNOW what my cellphone number is so that could not be wrong. I KNOW what my home address is so that could not be wrong. As far as I am aware my withdrawal limit is R500 so assume that is not wrong. I have never received an SMS when monies are paid into my account only when I withdraw or pay amounts greater than R500 so assume that my answer to that one was correct. WHERE does one see this information linked to your account because hell knows I have never seen it and have no idea where to find it. Because of this I was politely told that I was pretty much lying and therefore had to go into my branch to sort out my query.
