Frozen Account AGAIN

This is my third month with FNB and every month they freeze my account due to documents that they did not receive. And every time i go into the branch and Willowbridge and give in my documents and watch the teller scan the documents and open my account. Now again they did the same thing, leaving me with no food, petrol , elect etc this entire weekend and now again i need to go into the bank. I am most defenitely closing this account and suggest that nobody ever uses FNB. I will take this matter as far as possible.
