MTN managers failed me

I bought two phones online via MTN Mondo (MTN Rewards). Firstly, the delivery was bad the DSV driver never pitched after I was told he’s on his way.. had to leave work around 6pm, waited for nothing. The following day, I called in and the delivery date was rescheduled and received both phones after two day, which was 31st of January 2025 if not mistaken. After a day or two one of the phones was overheating and having electrical shock , on the 3rd of February 2025 I went MTN Springs Mall and they said I should go to MTN OR Tambo airport because they can’t assist me and they don’t take phones bought online. Then on the 5th of February 2025 I decided to confirm if I should bring the phone to them at MTN OR Tambo and they also said why should I come to them when MTN franchises can also help.. I was tossed to and fro. I then called MTN Mondo, they advised me to do collection…which I did and app**** for. On the 12th of February 2025 I received a call from DSV saying they are by my house to collect the phone, I was actually shocked and not impressed with the ongoing poor service DSV has been giving me…I then had to rush home leaving work to give the driver the phone(who has been bothering me to hurry up since they are being tracked) all of this led to the phone being switched off only and forgetting to unlock it and remove”find my IPhone “ , another issue I didn’t even receive a collection receipt. After few weeks I called in, calling MTN mondo and DSV to find out the whereabouts of the phone and no one knew. After a month I was told by DSV (Ms Ndlovu)that the phone is at the MTN warehouse and therefore “there’s no need to worry about the collection receipt “ Fast forward, there was no communication even after two months, I had to check in and even asked for a reference number which up until today I do not have. The lady (Hlengiwe)from MTN Mondo who told me MTN warehouse sent back the phone because I have to remove the “find my IPhone”, is now no longer working for the company..therefore I am once again stuck Two weeks back I called once again, one of team leaders at MTN Mondo Siyabonga promised to call me back but never did, when I call he’s always on meetings. Every consultant I speak to at MTN Mondo seems to be clueless, all saying they’ll “escalate the matter”, my question is to whom is the matter being escalated??? Now worse, the last call I made on 30th of April 2025, I was told MTN warehouse system crashed therefore there’s no records on the system. DSV on the other side only has the delivery of the two phones on the system and nothing else Now what should I do, where must I find help because monthly debit orders by MTN Mondo are continuing without me getting assistance!! Where’s the device and why am I still paying for a device I do not have
