Phone out for delivery for 8days

My new phone that was giving problems (3 days old) was sent in for warranty assessment as the scratch my cover made on it seemed to be alarming. The phone was picked up from menlyn mtn on 04/04/2016.<br> I received a message stating this on 06/04/2016. I phoned the repair center on 07/04/2016 and they said it is still on route. 11/04/2016 i phoned again and to my surprise MTN cannot pick up my device, they cannot give me ANY information and gave me THEIR courier companies number - I the CLIENT has to phone to hear where my device is when MTN arrange a courier and a pick up - see latest and ONLY tracking reply: 2016/04/04 03:58:36 PM Out for Delivery with Driver. Thus IF it gets to the repair center - i now have to believe that my phone was \SAFE\" for 8 days but nobody can confirm where it is. I will not take that device back MTN you can mark my words. For all i know that was used and misused and damaged, and when you give me feedback it wont be fixed due to damages - BY WHOM if you courier company had it missing for 8 days?????"
