No service at all

I went to the branch to close my credit card account. We phoned the call centre but they were closed (why would the branch process be to contact them if they have already left?). The banker assisted me in completing the cancellation form and was sent on the 24th. I was told they would contact me the following day which did not happen. On the 30th I was called ans asked to phone me in 20 minutes as I was just finishing up in a meeting. Not a problem I was told! Two days later and after follow up emails nobody has yet contacted me?? This is now more than a week and I have not yet received a single word from FNB nevernind closing the account!!
