FNB does not want to close settled credit card account

On the 2nd of May 2018 i phoned FNB to settle my credit card account and close it. I got settlement amount and was settle on the 3rd of May. I phoned FNB and got referred to credit card department, they promised to log a call for closure and will receive a call from the department within 7 days to confirm.

Its the 10th of May 2018, and I still haven't received any call from FNB. Question is do they want to close account or not? Ok, or they want me to access the money and be in debt again? Should I close all my accounts and move the invested R850 000 to another bank? Extremely disappointed with this bank. Maybe its about time i find a new banking home. This is not the first time.
