Cellphone Contract Upgraded but no Phones Received

I recent upgraded my cellphone contract by telephonically with MTN Direct, Mtn Account No: A ********** ( ********** ) for Black Friday Special for 2 x Samsung Grind Prime Phones for R199pm on 27.11.2017 assisted by Samuel Tsiame. On the 05.12.2017 i received only 1 phone instead of two phones and a sim card(the new package is activated), i then called MTN Direct again to report the matter then Samuel Tsiame inform me to return the phone to my nearby MTN shop so that the courier will fetch it to warehouse and i did so.I have been waiting since on 05.12.2017 till today and calling mtn everyday with no luck, they said they are forwarding the matter to their supervisor and he/she will call me back but they never called me back. Its really frustrating because the phones was meant for Christmas gift and now am paying a contract without phones.
