Upgrade unsuccessful super unprofessional

I have placed a telephonic upgrade on Tuesday the 28 August 2018 for a Huawei Y 3 2018 model for u choose Flexi 120 for R99 a month Since i placed the order i have never received the phone

I have contacted the upgrade department 3 times each time they have informed me that there is trouble with the courier company with how many excuses, which at the end they told me on 06 Sep that i need to contact the courier company as the phone is with them and its out of there hands now.

This morning 08/09/2018 at 10:00 i called again where i was informed that due to the courier company send the parcel back, my order needs to be cancelled and reloaded and that some one would contact me.

AT 13:30 i had to call again as still now one has contacted me. where again i was informed that I need to replace my upgrade and due to that the special on the Huawei Y3 2018 is no more R99 but now R129.

This is the worst service every now i need to pay more due to other peoples mistakes.
