The Worst Bank!

What a mission it has been to get a paid up letter from FNB Credit card department, i have sent numerous emails with no response. I even phoned in a couple of times and it was said that they would send it and its been 3 weeks with no paid up letter. Besides that a consultant advised me that they cannot assist me with the verification process because i do not have an app i have not been with them for many years and the account I had i have lost the card years ago. Now i need to go into a branch so they can verify me as they cannot do it on my cellphone why is it such a mission just to get a paid up letter and no response. Highly disgusted in how you treat clients and the turnaround times for something as simple as a paid up letter!
