MTN — Extremely Disappointing!!!

I've been an MTN customer since the early 2000's. My last contract ended 9 August 2021 and as many calls as I received to upgrade, I refused them all letting them know that I was waiting for Black Friday. On Black Friday, I find a deal online that I apply for. On Monday, I receive sms'es letting me know that I'm being vetted/processed and within minutes I am approved for the upgrade and told that I would be contacted for delivery details and even receive a copy of my contract. The following day (Tuesday) I am contacted by the courier company and I verify myself and confirm my delivery details for delivery the Thursday between 1-2pm. Thursday I waited anxiously but no phone. Friday I call the courier company who says they were instructed to return the package to MTN. I call MTN and get the run-around and nobody able to give me an answer. By Monday afternoon (and dozens of calls later), I reach somebody who finally tells me that my contract was cancelled because they erroneously had an additional address (in another province!) for me and so the package was recalled and my contract was cancelled. They did not bother to communicate any of this information to me, I had to chase after answers and eventually be told that I no longer had the upgrade available. They then tell me to go instore to sign up for a package and quoted me even better prices than I had signed up for online. I call different stores and eventually somebody answers and tells me there is no such deal at any of the stores leaving me without my desired package and extremely disappointed in a service provider whom I had been loyal to for nearly 2 decades! They made NO attempt to fix this problem or even to try and retain me as a customer. All I got was an "I'm sorry, but there's nothing we can do". So I am sitting with a contract which was sent to me but no device and zero care from MTN. How is this fair when I did NOT cancel or give incorrect delivery details. They messed up and I'm paying the price!!!!
