Bad service at MTN client service for an upgrade

I app**** for an upgrade on my MTN contract on the 11 August 2021 with the following order number": ***. I have been trying to follow up on the status of the upgrade. I constantly told that it's still pending. another person would say it has been cancelled. the other person will say, they cannot access the account, as only the person assisted me with the upgrade has access to it. today I have yet again called MTN client services on *** and spoken to three different people who told me three different answers on the same order. Lastly I call client service on 135, and received a different answer that, the account is still on the vetting stage. MTN client services is disgraceful to say the list. after holding on the line for 5mins each time, I get different answers and I am left more confused than before, begs me to wonder why am I still have a contract with them??
