I as a widow am getting shocking treatment by Absa

My husband opened his Absa account 40 years ago and he and I ran our bussiness from this account. It was a T/A and we used it for our bussiness of 40 years. My husband sadly passed and I am in the process of changing the company to a PTY. Our main bussiness is that of building contractor for various insurance houses. The change over of this is a timeous process,. Absa has put a lock on this account and even after the excecutor requested that the lift be removed do they still leave it there. I cannot pay salaries or buy materiaal. My debit orders do not go off. And I was now informed that due to Fica issues this account will be closed within 5 days. I have not even been aware that there was Fica problems. I was not informed of this. It is shocking and heartbreaking that I am being treated like this, as a widow life is very difficult and now our bank of 40 years just give me a kick while I am very vulnerable. Instead of assisting me they make my life very difficult. I am very disappointed with you Absa after 40 years this is how you help me.
