ABSA Likes to de***** its customers

I have been tried to cancel my credit card with ABSA several times. The last time I tried in November 2018 I paid the account in full as requested by the teller and answered several questions as to why I was closing my account I was then informed that the account would be closed as requested. In December I got a notice of outstanding amount and threat of credit rating being affected. I lodged a formal complaint on the 17th whereby I was informed that the complaint would be investigated. The last email I received informed me that I would be contacted no later than 22 January 2020.Needless to say 22 Jan came and left!. It is now 24 January with another email and sms to pay outstanding fees accrued after closing my account!. I have never had such bad service from a band. Pathetic to say the least. If not resolved soon my only option would be to lay ***** and ******ion/racketeering charges with the SAP and approach the ombudsman.
