Account opening delay

I opened a new account with FNB on the 13th of October. I completed the requested documents timelously. To date the account has still not been activated. I called to find out the reason and was told I was missing a document which they apologised that they had not yet sent to me. This document was returned to them last week Wednesday and resent today. I have called multiple times and get told that the account will be activated within the 3 day turn around time. The matter has been escalated multiple times. This has been going on since the 20th of October and is well out of the 3 day turn around time especially considering that the account was opened on the 13th of October. Is this how long it normally takes to open an account with FNB?
