Frozen account

Good day im not happy will service that i have recieved at FNB ***** Department it's been months now still no resolution from them as they Freeze my account and did provided them with the full documents that they requested from me . The most stressing i have been communicating with Lunga Bottoman he doesn't respond if he respond it will be after a month or not at all . The last when i spoke to him he need the invoice so that he can resolve the matter till today the matter is still not been resolved .
