MTN Insurance

I bought an iPhone 11 Pro from MTN In October last year, within one month it had Started giving me problems where it would go on and off all willy Nilly and at some point it would go off for 4 hours at a time, I took it in to MTN in December and they took it to warranty, warranty apparently found nothing wrong with it, I took it back and within 3 days it started giving me the same problem, my back camera had cracked by then so MTN told me they cannot take it to warranty and it has to go through MTN INSURANCE, my nightmare began here: Insurance took more than 2 weeks to fetch the phone to be repaired and took 3 weeks to bring it back, when it was brought back they fixed the back camera and not the software issue it had, I booked the phone in for repairs AGAIN the following day, whoever was booking was so ***********, the phone is since at Repairs

1. I really feel like I got the wrong batch where this phone is concerned, I have essentially had the phone for 6 months and I only used it for 2 months, this whole year I am paying for a phone I do not have, because of a technical fault.

2. I DO NOT WANT THIS PHONE BACK, it clearly has a software or functionality issue that I am tired of dealing with and that your technicians clearly can't identify and they keep returning a phone they claim to have fixed

3. I have lost my patience, who's phone am I suppose to use in the interim because I can't use the phone that I'm paying for ????
