MTN Worst Customer Service Ever, 22 Loyal to them, disgusting.

I've been a loyal MTN subscriber for the pass 22 years, my account has grown further that I have an additional 2 contracts linked to my account. My problem started in April, when i received a call from what i was told was a MTN agent, with regards to my upgrade of my accounts, which was due already for about 6 months. I asked them to call me back as I wanted to first check what was on offer for each contract. She then gave me different packages on off and what she could even further offer me. I still asked her to call me back in a couple od days, which she did. By this time i had checked MTN's website as to offers. I upgraded the contracts, biggest mistake to date that I made, my account has been messed up and I never recipe what was offered on packages, only thing that i received was the phones almost 2 months later, no paperwork nothing included. Upon requesting it i was told the upgrade was not done by MTN but by a agent that does marketing for MTN, called Mobileplus. Tried calling then, no answer tried emailing them still no answer. I've been dealing with MTN customers service and still in the pass 2 months I cannot get anyone to rectify my messed up acvount, our data deals are incorrect, my acvount the main account holder has also got the incorrect voice minutes, I've can quote you a list of references numbers that I've got from MTN Customer services thats resulted in nothing. This month my daughters account never received any normal data, but recived her night time data, I'm now spending more money buying data and topping up my voice bundle. Right now I want to canel my contracts and tell MTN to go to hell. Not even there so call back office where agents have directed my complaints to have come back to me or even sorted out this problem. This issue is going on since April we are now in July, its been 3 months of no response. If MTN cannot get their so called agents working for them to do their jobs what the hell am I even being loyal to them for.... And please Corona virus and lockdown cannot be an excuse for this bad service, even if they working remotely.
