Cant access MY own money.

I app**** for a CC on my mobile app. It got pre-approved. I signed the agreement/contract and sent it back. Before my CC even arrived, let alone activated, it was available on my mobile app. 1st stuff up. 2nd stuff up - I was able to transfer money onto the CC (by accident) 3rd stuff up - I have no access to MY money and cannot even transfer MY money to one of my other accounts. 4th stuff up. The FNB credit department seems to be a bit slow and backwards and seem to be unable to reverse the transaction. Surely there must be a straight forward, SOP on how to reverse a transaction???? Going into week 2 now and still waiting for a resolution. I have no CC, and I cant access my own money. lol

There are alot of other banks in SA. I don't have to be with FNB.
