Pathethicaly bad Service

African Bank offered me a 50% discount on my credit card of which I have been trying get rid of for almost 8 years , I took the discount and they said to me they will debit my account on the 07th October 2020 which I was fine with , they debited the money on the 07th as aggreged , so come the 24th another debit for the amount that was paid on the 07th , I called them so the first consultant advised me that I should call back the Monday 26th as the amount does not reflect and I should please send them proof of payment , I said no problem , Monday came I called again the 2nd consultant told gave me the email address to send the documents he also sent me an sms telling were the documents should go , he then logged the query for a refund, so I call in on Thursday just to find out if they received my documents and the consultant that spoke VERY rude told me she doesn't know and I should give it 48 working hours and that amounts to 5 working days , cool, I leave it then on Friday Morning at 6:30 I get an sms that they still waiting for my documents they requested on the 03/11/2020 , how can you request documents on that date when we are still in October , so I call again and the lady Tandeka gave me 3 different stories about were my refund application is and once I started shouting she then told me no it will be dealt with that Friday or lasts Saturday, today Is Wednesday and still nothing evetime I call they tell me the busy with it I have been sending emails and emails with no response , they called me yesterday to make payment arrangements and the guy I spoke to I told him I am still waiting for my refund what payment arrangements are looking for, the ***** statement they sent, a lady by the name of Shelia called while I was in a meeting and then sent and email that she tried calling me numerous times but I didn't answer , please assist I really need my money and African Bank is giving bad service and nothing is being done.
