Issue not sorted out within 48hours

Being an FNB client for more than half my life, my home loan, car finance, savings and tjek account all with them, I am extremely disappointed in the service I have received this last week. My revolving credit has just been cancelled (no access) from the 1st of March. After probably 20 calls to fnb premier banking, this is still not sorted out. Apparently Mr Roux Pretorius (credit manager) has done his job and lifted the restriction that should have never happened and fnb has apologised for as it was loaded wrongly...Still Mr.Roux Pretorius has not been successful in lifting this \mistake\". Every time I phone Mr. Pretorius has left already, is not in yet or has lifted it already Miss Willemse....this was lifted on the 8th already and will take longest 48hours....but it's now the 11th 5pm and nothing has happened successfully. Fnb your staff really disappointed me, especially Mr. Roux Pretorius credit manager of premier banking. I have been offered private banking from fnb....wonder if private banking will also take this long to sort out something they have wrongly created."
