ABSA CREDIT CARD DEVISION

I have been receiving numerous sms's and missed calls from ABSA regarding my credit card on which I supposedly have an overdue amount on. I phoned thir given number ********** 272 and spoke to a Patricia. She assured me there was nothing wrong with my account and that it was up to date. She said she was escalating the problem to another department and assured me that I would not receive any more sms's or phone calls. Hahaha...............a week later and I am still receiving sms's and calls. I take exception to this. Please sort it out once and for all.
