Freeze Account without warning

Useless FNB send me an sms for the first time to informe me that they are going to freeze my account, because they want my proof of residence and ID, I had no warning. So today my account is frozen. How the hell do they do business?Now I don't have anything on my name to give as proof of residence, everything is on my husbands name. Now he is not at home and will only be back on Friday evening. Now tell me how the hell am I suppose to feed my children if I can not draw money because you fx@#%. up???? I will never do business with your bank again. I am a customer for how many years and this is how you treat me???? You can take your bank and shuff it up some were. Any person banking with you must go and get their minds read. I want my account unfrozen immediately and after that you can all go to hell for all I care.
