Poor expertise/service from Standard Bank Credit Card facilities

Hi,

I am a Standard Bank client (for the last 9 years) who have closed my credit card account and destroyed the card in February 2017. Three months after the account was closed, I have been receiving notifications/letters from the bank urging me to pay my balance.

I have complained about this and the bank acknowledged their mistake and said they will fix the issue. Few months later, and I still receive these letters and have complained at my Bank branch (Alice Lane), Sandton. They advised that someone from the ***** department will contact me but I still haven't received any calls and keep on receiving their sms notifications urging me to settle my account.

I seriously sick and tired of this poor service and require this matter to be solved and closed.

How can a closed account still charge fees and also perform transactions which didn't even originated from me?

Regards
