FNB froze my accounts wrongfully

I am so frustrated with FNB. I opened my fnb bank account earlier this year. They kept on telling me my FICA documents are not correct and then I send it in and I get a reply that all is in order. A few weeks ago I get a message that they are going to freeze my accounts if I dont hand in the FICA docs. My fiance and I went to dotfnb on the 21st where we handed in new documents and they said all is in order. The 22nd I get a new sms that the fnb fica documents are outstanding. I phone them they say it's correct. On Monday I try to pay for goods and to my embarrassment my accounts are frozen. Phones fnb yesterday and they said they have a problem with the address as the street number is different on the electricity bill even though it is the same stand number and a corner house. All my debit orders can't go through and now this is going to count against me and no one can tell me when this will be fixed. I don't have access to any funds and fnb just doesn't care at all. Utterly disappointed.
