Worst customer service

We took out a two contracts with Mtn on December 19. Wonderpark agent who helped us said we can collect on monday. This was my kids`Christmas presents. To date we still do not have the phones. Neither the call centre or the shop seems to care. The store says call the call centre and the call centre says go to the shop. The shop said that they are small and do not get preference on deliveries and that it is `unfair`for me to threaten to cancel the deal! I have sent several facebook inboxes with only one response, are you still having the same problem? If you did not do anything then YES! I have never experienced such bad service and is utterly disgusted. I am looking at cancelling all 4 contracts I have with MTN.
