Ridiculous service FNB

I have a Premier Cheque Account with FNB. I am not happy at all, last week I received notifications of purchases on my card while sleeping and having my card with me, when I contacted the private banker about the matter; I was not told they cannot help me. I then blocked my card but still i was receiving notifications of purchases declining because my card is blocked. as a result; R629 worth of charges were incurred. i have not been using my card or account anywhere but I have to suffer charges i do not know anything about. I am at the point of moving my account to another bank because of this. not even a single attempt from the bank to fix this, instead they are calling to offer me a funeral plan.
