Bad service - FNB

I transferred funds to my credit card, however, FNB claims that the funds were transferred to some account handed over to collections but was closed years back. I always do this transfers and don't understand why this account randomly came up on Saturday. i called the call center yesterday, the lady who assisted me was rude and not listening to me.

I called my banker this morning - can never get hold of he/she but im charged for the service monthly, what's the use if i have never even heard from my banker. I made 3 calls this morning, 1st call was disconnected, 2nd call - the lady placed me on hold for over 20 minutes while investigating, she never once came back to say that she's still investigating or if i would like her to call back, i ended up hanging up. I called again i'm still on hold, for collections an hour later. I trusted FNB , i was wrong . I'm even considering moving my account.
