Phn disappears in store n appears when i complain

In August my handset stopped charging and I sent phone back to store which was booked in and sent for repairs by Ganeth and was returned in September. However same problem started and I returned the handset Nov 2oth booked in by Ganeth again and was told TAT is 2-3 weeks. The 17th December I went in to enquire and was told there's no records of the handset on the system. Jennifer called Ganeth as he was now in a different branch to check whereabouts of the handset and he said he didn't know, somehow handset was booked in to repairs centre on the 19th December by a Ghost since no one knows till today. Handset was returned 3 days later and the screen wasn't working and I booked it back again. I then asked Supervisor Jennifer what will happen now since handset is going in for the 3rd time she said they will send through motivation so my handset can be replaced, and for me to be credited since I dint have the handset for so long. Matter was referred to Alana Gleed manager who never came back with feedback. Then again I asked for Lerato whose the Area Manager to contact me and she still hasn't a week later. I logged a complaint on MTN website REQ:*** till date no answer.
