IMPOSSIBLE TO GET A HOLD OF

I upgraded my contract in Nov 2015 and the phone was giving me problems so I took it in to the repairs centre, 2 weeks later after my phone was apparently sent back there twice beacuse of some \missing wb\" they approved a new handset and I was advised by mtn to choose another phone as the sony xperia m5 has been recalled and was giving a lot of problems. I have left dozens of messages and emails for Tiny the supervisor at Mtn jhb to phone me regarding this replacement and have yet to hear back from her.When you can actually get through to mtn direct she is never at work yet is apparently the only person in the whole of mtn sa who can help me and it is beyond frustrating I did not ask for a damaged phone so why am i made to suffer because someone can not just pick up the phone and call me. Its into the 3rd week and mtn is still happy to take my money for a phone I don't even have.Someone needs to contact me today to sort this out or the next call i make will be to cancel this contract, don't see why i must pay for a service i don't get.<br> <br> IMEI no:*** /ref no for one of my calls *** /collection no:***/MTN active reference number is ***/Ref no118925"
