HOLDING ME HOSTAGE!!!

I settled my credit card last week Thursday and requested to cancel it. Friday I then spoke to a consultant at Nedbank: *** who then advised me that the request was logged and that I WOULD NOT BE LIABLE SHOULD ANY SERVICE FEES BE CHARGED THEREAFTER. Today I then get a call from NOSIPHO *** who tells me actually I need to pay outstanding fees on the card before they cancel it Firstly i was told i would not be liable should any fees be charged after my request as I settled the full balance and today when I look at the account I can see that Nedbank actually needs to refund me a R5. not really worried about that R5, my point is just that its actually in a positive balance. Then this lady wants to tell me that the fees was not from today its actually fees that ran already which is a load of bull* as I can clearly see on my app that fees were charged on the 16th of Nov and that there are no fees pending. The account is fully paid and fees were covered yet they still trying to get money out of me!!! Then she wants to say I must understand? Understand that you guys want to RIP ME OFF??!! Because I had to first hear a load of nonsense before you guys actually decide to process my request. I BETTER GET CONFIRMATION THAT THIS ACCOUNT IS CANCELLED TODAY OR I WILL GO TO THE CREDIT OMBUD AND REPORT YOU GUYS!!!!!!
