2 Months into my contract , waiting for my 4th phone replacement

About two months ago i took upgraded my MTn contract , i purchased the samsung galaxy s8+. a few days later the phone went faulty. I got a replacement a week later , within a few days the new phone started issues , and i went in to get another replacement. This time it took two weeks for the replacement. i got a new phone yet again , this time it gave problems the same day . i took it back to the store the next day. three weeks later i am still waiting for the new phone to come. i got into contact with the repair centre and spoke to a guy by the name of Andrew who said he woulld contact me the same day with regards to the order. while in conversation with Andrew he gives me some pathetic excuse like couriers . In any event its been a week and a bit , and NO contact from anyone. i phoned the store as well to enquire but even the manager refuses to return calls. MTN IS PATHETHIC, i would not recommend Mtn or any of their subsequent services to anyone out there. You will get no information or assistance with regards to your issues , all you would get is a bunch of empty promises, but more importantly a bunch of lies!!!! If there was a ratings score for professionalism , i would get them a zero.
