FNB Upgraded my account without my approval

Not Happy with the service i recently received from FNB, firstly FNB upgraded my account to Premium without my approval ,then charged me R229,when i complain about it 2 weeks back ,i then receive a call 2weeks after which is today 07/06/2022 that they will downgrade me back to Aspire …now what **** me off is the fact that FNB told me that i will be charged for something that was not my fault...Please FNB downgrade my account back to Aspire and refund me back please ..
