MTN upgrade nightmare

how can i put in words what was already echoed by so many complainants on hello peter on MTN's shocking customer service. let me try... My nightmare began when i tried upgrading on their mobile app, I had to apply numerous times only to be bombed out, I then logged a call for a callback and that worked 2 days later, i was contacted by the sales consultant whom advised me to leave everything in his hands as he is working on what i app**** for. when i received my package i was surprised that there was only 1 phone when the original deal was for 2 phones, i immediately contacted the consultant and he said that i should not stress and he was going to sort things out. this was on Monday the 18th July 2022. i then lodged a complaint as the consultant did not call me back and was told by a call center agent that they will send a mail to the consultant, Tuesday morning i get a call from the consultant and he suggested that i go to a store to return the phone and get a ref number. the store that he suggested could not help as they are not a affiliated to the MTN head office. i then went to the 14th avenue store and got the phone booked by a very helpful consultant and we then contacted said agent with the ref number to cancel. the agent did not want to cancel and his management had to get involved as he refused to cancel the deal, even though he made the error in the first place. it is now Friday the 22nd July 2022 and i have no phone, a contract that has already been loaded and no response from MTN management over any of my complaints..... One wonders if this hello peter will even be picked up by their team.
