Poor service of the frozen account for so long

What a selfish bad service from FNB, They froze my account from Monday, apparently they wanted foreign tax documents that they didn't even notify me with,I went to the branch and submitted those on Tuesday, they said whatsoever process of theirs takes 24 hours for them to unfreeze my account, I have been calling to no avail,these selfish people dnt want to open this account of their, I want to close it I can't use Fnb anymore,its so selfish, can anyone tell me how I will get my funds when I close the stupid account. At Birch Acres mall branch they said I can't even close this stupid account if its still frozen. This is so unacceptable.
