Credit card issues not sorted out

I got a phone call from FNB saying that my credit card was being upgraded from a fixed pay to a classic credit card and my current card will be cancelled. I went to fetch my card at the olympus branch and my current card was not cancelled and the balance was not transferred to the new card. I eventually landed up in Jaques office the branch manager. He has been in contact with me last week and has been trying his best from his side.he says they having problems in the credit card department and it will be sorted out asap! I posted a post on Facebook to fnb and someone phoned me where I said I I'm extremely unhappy that the problem has not been sorted and that the fact that I have to pay a R150 initiation fee when fnb upgraded me, I shouldn't have to pay that fee and the deducted it before things were sorted, the woman I spoke to said I must spend R500 for 3 months and the fee will be reimbursed, I said that I want to pay it off not spend on it she said just do it and argued with me and the proceeded to laugh at me. It's been almost 2weeks and it's still not sorted out. This is seriously unacceptable!!!
