Credit Card

Good day My FNB credit card is showing an available balance of R0 Have called through to the FNB credit card department who advised some documents are outstanding. They have transferred me to various departments without any joy and the call just gets dropped after a certain point When I called again the 2nd time the consultant mentioned that they see no block on the account hence I cannot understand as to why the available amount is on zero. Yet again after trying to transfer me the calls get dropped. On the 3rd occasion the consultant said they have mailed the relevant departments to uplift the hold, and also tried transferring me without any luck Please will someone get in touch with me Thanks
