Huge loss to business due to FNB bank account

I am extreme disappointed with FNB for freezing my new business account and once we had all the documents sorted out, it turned out that they or their system were the ones at fault, as I had, from the beginning supp**** all the correct information. Now I am unable to recieve any payments for my business while I have to wait for their system to update, and there is a very small chance that I will be able to get all the funds lost due to payments not being able to be made to my account. I am extremely sorry for using FNB as a business account and really wish I had not. Not only did they unnecessarily freeze my account, but the lovely lady who went out of her way to help me apprantly got into trouble for apprantly not giving the correct information - however, it turned out in the end, that all the info supp**** was 100% correct. I have lost quite a bit of funds due to this. I cannot give this bank a thumbs up at all and I wish I had rather stayed with ABSA. How on earth would one even know that your account could be frozen - none of this was explained and the account was open without any problems. I cannot believe that my business has to take a loss because FNB could not get their systems or processes in order, and they face not consequences whatsoever for this
