FNB bad for business. Worst experience since

Today I got an email from a Wendy Majola and her manager Mahlatse Mashia who had informed me that she will be suspending my business account because of an eft that we made into our business account she requested source of funds which I provided at 8am she did not confirm receipt of my email or bother to inform that my account will remain closed days to come meaning I can't pay for stock which I have ordered for my shop I can't pay my shop fitters I will be closing my account with FNB I will move my business to people who look after my interest oh by the way Mahlatse has been unavailable (Snuggle Barn n Bags)
