Still no feedback on credit card problem.

This will be the third Hello Peter report that I will be writing on exactly the same problem / issue. I closed my credit card account last year, not later than October. On the 15th of December I see a charge back of more than R6000 appearing on my cell phone banking app for this account. I was not informed of any problem in the past, nor did anybody tell me there is such a big amount going to appear on my account. I spoke to standard bank card division on the 17th of December 2015 asking them what is going on. All they could say is that the problem has been escalated. I had a response on my second report from a Amanda Mnothoza from the customer resolution centre apologizing for any inconvenience, but did not hear from her since. Every time they phone they say it is being recorded, I hope so. They keep on adding late payments and interest. I really cannot understand that they cannot resolve something as simple as this. I even got a lawyer threat on a sms once. Please Standard bank. Resolve this now.
