Pathetic service and a disgrace

I am in the process of buying a car! You gave me a letter confirming the account with Standard Bank Credit Card is paid up and that you will rectify my profile with the credit bureau. The account / card number on the paid-up letter is wrong or let me rather say not mentioned - the letter means nothing to me. The debt is still on my profile. You are pathetic. I have been calling you for days now asking for assistance and nothing happens. How do you operate like that????
