Repair Rejected

On the 26th of January I took my phone, which is 3 months old to the MTN store at Newcastle Mall, Newcastle, Kwazulu Natal because it heated up and kept on rebooting. The assistant, Lizelle completed all the documentation for the warranty assessment and inspected the device. She quoted \the phone still looks new and has no scratches"and she made me view it too before placing it back in the box. On 9 February I contacted the Mass Repair Center to follow up and was told that the Warranty Assessment was rejected due to incomplete documentation and will not be repaired or replaced due to a scratch on the camera lens and on another place. I know that there were no scratched on my device and the store assistant also confirmed this before the device was sent in so it must have been damaged in the care of MTN. So as I understand all of this my phone is being sent back unrepaired and will never been repaired due to the scratches and because the shop assistant filled in the documentation incorrectly. I find this to be very unfair towards me as I will be forced to use a broken phone from now on.<br> IMEI Number ***92 122"""
