Frozen Stokvel Account

I have a stokvel account with FNB which we opened this year and I was told to fill in forms that have to do with Foreign Business Tax which I did on the 27 of February, I kept receiving messages I was receiving I called the foreign business tax line they said no there was a page missing I must go to the bank again I went to the bank to fill it in with the missing bit of information. I then went to bank after they said my account has been frozen on which I spent almost an hour waiting for someone to help me, until I started getting really upset I eventually got someone to help me in that day I spent almost 2 hours. Yesterday I call they say my account is still frozen I must go back to the bank again to fill in the form??? I’ve already filled it in and signed 3 times your staff do it on the system as well. I am not understanding what the problem is. I am tired of going back and forth and your staff are failing to do a 2 page form they always say it’s done correctly but your call centre people tell me a different story. I don’t think it’s fair that I have to fill in the same form 4 times and still no solution from February till now it’s still not resolved. I’ve done it all 3 times at the Sandton City branch
