MTN doesn't care about customer service

I've booked in my Iphone on the 7th of January at MTN head office , they could not repair the phone freezing issue and quoted me R4000 to repair (review on Hellopeter), I rep**** to their quote to return my phone on the 20th of January , a week later i visited to collect but my phone wasn't at MNT , they assured me they will return my phone in a couple of days on the 13 th of February I received a message that my phone is ready to collect (2 weeks later) , when i collected my screen was damaged by the repair centre , I then booked my phone in again , today I receive a quote for R4500 to fix my screen , I asked the repair centre supervisor to contact me and he hasn't yet , if I do not get any help or contact by MTN by today I will Name and shame 2 managers , 2 service desc staff and 1 repair technician on hello peter , next step I will find one of directors's email adresses and send them every link of my 3 reviews on Helllopeter
