15 business days GOING on 30!!!!

Only after my review on 31 March 2021 at 10:58 am I was contacted by FNB. I was told what to do and I did it the same day. I want to close my account and transfer the funds into my current bank account. On Wednesday, Mar 31, 12:28 PM I sent FNB all the required documentation as requested. I was told it will take UP TO 15 business days. After MANY emails after the 15 business days, the issue is still not closed. It has been 29 business days????
