Incompetency of FNB credit card department

Last month (March 2022) I paid off my FNB Premier Credit Card, I called in FNB a lot of time to cancel or permanently close my credit card. On the 9nth of March 2022 spoke to a consultant by the name Tiiesetso she advised me to fill in a cancelation form and email to FNB, I did exactly that 2days ago my app shows the credit card account and that I owe R2. I called them again of which is a waist of time, was transferred to all the wrong department, spoke to one consultant who put me on hold and said his checking my account, never came back and a new consultant spoke on the phone( the high level of incompetency) she then **** and said she would contact the cancellation department and they would email me, that was 2days ago, till today the account is open and i owe R2 so clearly the charges will increase. FNB enjoys seeing people in dept. i want the stupid account closed. I don't want your credit card anymore. you don't even deserve a start at all call me FNB and fix your mess.
