Sick to death with FNB

I opened and FNB Business cheque account last year and since then I have regretted it ever since. I then tried to close the account at Northgate Branch and have had to go back 3 times and wait in a automated queuing system for a total now of 3 hours. The time I was there I was told that the account was authorized for closure, they were just waiting for costs to come off the account. The second time I went there because FNB sent me an email saying they were automatically closing my account and that I owed R200.00. I was again told then that the account was to be closed and that R40.00 was owed to me and it would be placed into my Standard Bank account. I AM STILL WAITING AFTER THREE WEEKS. Now, who do I invoice for my time, I have lost three hours of work time to FNB and I will bill for it because you are ***********, arrogant, have no clue of service and down right impossible to work with in general. Yes it is only R40, plus R1050.00 of my time lost.
