Highly disappointed in you guys!!!

I'm highly disappointed in FNB for the first time ever in years that I've known them. I had my account frozen because there was a "suspicious transaction" or a transaction that I needed to provide proof for. I couldn't use the account for days and after a lot of phone calls and emails back from me and the person who sent me money they were able to remove the hold on my account but after removing the hold they decided to now put the transaction on hold. The money is appearing under " reserved funds" I've been phoning in to find out where is the money, what's happening to it because I need to know if they have sent it back or why is it being held especially after we have provided them the proof they required. The lady named Khutso Penny Gram is the one who requested proof and she can't even respond to emails and give answers. When I call General banking inquiries or chat with them via secure chat I'm being told to call ***** department and when I contact ***** department they send me back to General banking. Yesterday at the ***** department a lady rudely cut the call on me after tell me she doesn't know how to help me, I didn't take her name but I'm sure it will be under records coz she did login to my account. Today I'm calling again for a follow-up they telling me investigators are not in they will only be available on Monday and they were the ones that were supposed to uplift the hold and they didn't. So if the investigators of the bank didn't do their job why must it affect me? Why can't the bank take responsibility instead of making me wait again until next week?
