Really don't know what to say HORRIFIED

So about a month ago I asked FNB to close my business current , my business credit card my personal credit card and my revolving credit account. I explained that I could not transfer funds to my business credit card as I am not in SA and the account is not on my profile. They have closed my business account that's about it. I have sent 3 hellopeter complaints to FNB and not once has anyone done a thing about this. I refuse to pay interest on any of these accounts as my request should have been sorted out
