Can FNB assist their customers for once?

Can FNB provide a better service for once and assist their customers accordingly. Late on 28 Dec 2021, I received a text from the app that stated R47 had been debited off my account of which I have no knowledge off. I logged onto the app and logged a dispute to gather more information. When I did that the app automatically blocked my card without my permission, when there is a temporary block feature I use the card for various online activities, I only asked for an enquiry into it. The online consultant then advised that I will have to pay R120 for the card in which I am not prepared to pay as I did not ask them to stop my card. A few weeks ago I had requested an upgrade as I was previously Premier and on the app it keeps declining why?? What is the bank going to do as far as the amount deducted from account?? I look forward to a detailed response as this poor service and inconvenience.
