Contract phone for Warranty Assessment

Obtained the Sony Z2 phone 5/01/15 in East London Hemingways, it gave problems and eventually booked in for warranty assessment on 12/02/15 at Pretoria Woodlands. Approval that it was faulty was on 24/02/15. Was then sent to the nearest MTN service centre in Melyn to collect a new device.<br> 24/02/15 Menlyn feedback - no stock available for Z2, I should PERSONALLY go collect the device in Wesgate or Secunda, there is nothing they can do as they cannot courier the device.<br> 25/02/2015 Menlyn feedback - should wait until they (at Menlyn) have stock available as I will not receive another device.<br> <br> I have been with MTN contract since 2010, do they not acknowledge loyalty? What happened to meeting customer needs? Cancelling my contract is the next best thing as the competitor will gladly love my loyalty!!
