NO HELP/ CUSTOMER SERVICE FROM MTN

I've been to 3 different MTN branches and all 3 were supposed to contact me back regarding my contract. I wanted to put the contract on my own name and it was due for an upgrade on 3/10/2023, so we managed to put the contract on my name, that nobody even phoned to tell me its on my name now. So I phoned the call center after holding for 13-15min I finally spoke to a person. The first person told me I can upgrade, and then told me the system isn't working and I was at work so couldn't hold on for much longer. Phoned again 12min holding and that person told me I should wait 24 hours and phoned again and that one told me 30 days... and again someone told me I first need to pay for 3months because I'm a new customer.. But if I open a new contract I can get a new phone? But I'm still a new customer, if you open a contract you don't need to pay for 3 months before you get the phone? When I asked that the person told me to hold and put me through to cancellations.. Been with MTN for almost 15 years now, will find another service provider that want to help me when this contract end.
