FNB just need to work on they customer service is totally disastrous!!!!!!

My account was blocked and after I contacted the person who I was instructed to contact called Thabo, he requested for an affidavit, proof of transaction, pof, all wish I sent to him and went to the bank several times to call him as he does not accept direct call. He finally unblocked my account and then placed my R80,000 on hold for reasons I can’t possibly imagine , his only excuse is that the fund is under investigation. He is talking about funds which I sold crypto for. I can’t understand this bank all I want is my money. You FNB can close the account for all I care but can someone tell this guy Thabo to release my hard earn funds ?? I have done everything he requested and all he could do is unblock my account and hold my funds like I can’t seem to understand how FnB feel good in making they customers suffer and beg them for something so easy. Please you people should release my money am tired of your games and jokes . It’s not really funny anymore and dem tired of it .
