Pathetic service and *********** people

I have 1 contract at MTN and my others are at another company, thank goodness. I was due for an upgrade with MTN and it has been the worst experience I have been through. Why are online upgrades an absolute nightmare? The staff in the call centre can't get anything right, just *********** staff. First of all I was sent on the run-around before the approval, then I couldn't get hold of the woman who was handling my contract, then there was an error with the application and now I have received the phone and guess what....it is not the right deal that I have received or contract I app**** for. Lets not forget to mention that I received some random whatsapp from an agent to congratulate me on my incorrect purchase and offer to add on accessories for a phone brand I don't have access too. I have tried to call the call centre so many times to get the phone collected and contract cancelled. NO ONE can help and I get given a number to call that doesn't even exist. Really fantastic customer service at MTN....NOT!

I just want this phone fetched from me and I want the contract cancelled.

My upgrade with another company took 3 days, this has taken weeks and it still wrong.
