FNB credit card

From the 1st March 2019 I requested my accounts to be downgraded from Private Clients to Premier. My cheque account was downgraded and my credit card was eventually downgraded but it took a longer and he spoke to several people from the call centre and he found no joy. After numerous communication with FNB and lodging complaint on their CARE system i was still not assisted. Emails were sent to Willem Nel and Kristy Forbes and the matter was escalated and neither of them could get assistance and the fees kept going off. On the 26 Aug 2019 I gave FNB bad rating after that nothing still happened. The ref for the bad rating was RB*** and nothing has materialized. I have been charged banking fees and cant get assisted. I have been struggling since then till today. I would like the fees to be reversed from the date the deposit was made into my investment with the idea of not paying monthly fees like i was advised.
