Standard Bank HARRASMENT

I have been harrased by Standard Bank. They keep calling me saying that I have a credit card with them of which I keep telling them that I do not have a credit card with them. The advisor I recently spoke to FORCED me to say that I had a credit card with them, saying that I made a payment arrangement in December, if which I did not. I asked her how do I make a payment arrangement into something that I do not have? She then went to say that I made a payment of R100 in December and again, I asked her, where do I get the banking details to make payment. She continued to bully me until I hung up the phone. These people call me EVERYDAY, this has now turned into harrasment. I will never advise ANYONE to bank with Standard Bank because they use other people's details to force non- clients to pay for their clients who have defaulted in their credit.
