FAULTY GADGET,SEND IN FOR REPAIRS 4 TIMES BY MTN

My account no: A***<br> <br> I did my upgrade on the 08- 01 -2015 to a Samsung SM-910 Galaxy Note 4 Gold CT, my contract expires in 08.01.2017. I did the upgrade at MTN store in Festival mall and was assisted by Nicodimus Shunmugam(sales person)I used the phone for a period of 4-5 months and it kept on giving me problems during that time, because I had a spare one ,I would swap them around all the time. I stopped using my new phone for that same reason. I then decided to use it again just to check if the problem persisted, this was now month 9,went back to the same store, explained my frustrations, Nico then suggested we do a simswap,I left the store to give it the maximum time to reload my data, same problems persisted. I went back to the store on the 3 October and they booked it for repairs.After 3 weeks I was called to collect again, same stories,got an error to say that 'not registered on the network ,it was not even charging.They took it back for repairs for the 4th time, got a call back to say come collect on the 1 Feb,hoping for a miracle,the agents decided to test the phone before i could collect and still was not working. The phone is still with them as on this date 16Feb16.
