Not happy with the service I received from FNB.

I have a revolving loan with FNB and I paid it off but didn't close it because I left it for emergency. I called the Call Centre on Wednesday and spoke to different Agents asking them why is the money not reflecting and all of them said they don't know because it was suppose to be reflecting. They escalated the issue to their managers and according to them this issue will take three days to be resolved. Today is Saturday and it has not been resolved after calling them everyday since Wednesday. I would appreciate if this matter could be resolved urgently..... Not happy with the kind of service I received from FNB.... My number is **********
