MTN Upgrade - Unacceptable Service - Still Incomplete

I have been busy with an upgrade for the past 7 days. The system says the upgrade cannot be completed until my email address has been verified (which it has been) Go into the store and it gives the same error. The consultant logs a ticket, no response, logs another, no response, 4 tickets have been logged and not one has been resolved. Keep in mind, tickets are attended to and resolved within 2-24 hours. I have gone into the store every day for the past 7 days, sit around for 2-3 hours at a time to hear the same thing “I need to log a ticket and a remedy ticket” Tickets clearly are not working. Stop logging tickets if the 4 tickets you have already logged have not been attended to! Phone someone! I receive OTP numbers to my Email address (which they say is not verified) however, I have the emails and SMS messages to prove otherwise. 7 days for an upgrade which STILL has not been completed because of an email address that says needs to be verified which has been done. No one can give me an answer This is unacceptable! What is going to be done? When it this going to be resolved? Is it ever going to be resolved? I need an answer!
