FNB - poor service

I bank with FNB and for sometime my card wasn’t working. Every time I tried to do a transaction it would say “ this transaction is not permitted on one of these specified accounts”. Bare in mind I also hadn’t used my card for about a month. So on the 22nd of January I decided to contact FNB so they could explain to me why my transactions weren’t going through. I won’t specify names but I was told that they had blocked my card because someone had sent me ********** money and that the matter was being dealt with by the lead investigator. They said that the lead investigator would give me a call as soon as possible. I waited another week and I called them again on the 28th of January and they told me the same story and that this time their lead investigator would get in touch with me on the same day. It’s now the 2nd of February and nothing has happened. No one has contacted me to say “ these are the next steps taken to deal with your case”. I’m just being left in the dark with nothing but a card that doesn’t work. This situation is very strenuous for me as I need money to do daily activities. I’ve left other banks for FNB cause it’s better banking but since this situation I don’t feel prioritised as much. I’ve waited for about 2 weeks now for FNB to sort this out and I’ve run out of ideas.

I hope someone hears my cry.
