How can you do that

Absa wrote me email asking for docs for FICA. They do have all the docs for over 8 years with them. I send them all the docs again, but one of which my accountant must supply. He is not available right now and I informed the bank as such. They mail me and say no problem, yet they put my account on FICA hold since Friday \MONTH END"can you believe this. I have 2 dependent to pay and look after one is 83 yo. Now I can not transfer money and they can not buy food. I am more than 50 years with this bank since they were SAS Bank but it is time moving to another bank ASAP."""
