Does not care about their customers Mtn Queenswood

I upgraded my phone about 7 months ago. Got good service due to a sale for them. Last month my phone just went dead, could not switch on or charge. Phone only 6 months old Sony Z3. I hand in my phone for repairs at Mtn Queenswood on the 28/10/2015. I was told it will take about 3 weeks. 2 Weeks gone by and no word what so ever so i decided to contact their repair centre. They told me they send back the phone due to no IMEI number on the repair request. ******** story, on the phone self you will find the IMEI. I decided to contact the owner Isack regarding the service and lack of communication. He promised me that he will arrange to send his driver the next day through to get the phone in for repairs. Still no communication from his side as promised. After 2 week again still no communication what is happening with the phone, so I phone the Mtn repair centre again to find out the progress on my phone. They confirmed no info by them regarding the repairs. I phoned Laurika at Mtn Queenswood to find out what the hell is going on. She confirmed that my phone is still by them must still go to the repair centre. BAD CUSTOMER SERVICE!!!!! ...
