Waiting for my upgrade phone for 2 weeks

I received a call from Selindile 13 Sep 2017 to inform me that my contract is due for an upgrade and she was calling to assist me. We processed the upgrade and advised that I would receive a call from the couriers to set up a delivery time. Since then, I have heard nothing. Ive called MTN on several occasions and been advised the couriers have received all the paperwork and will be in touch. This morning I called MTN again, this time they transferred my call the DSV Couriers, I spoke to Rivonia who confirmed they have no order on system for me. I called MTN back and spoke to Olivia who took my number down after speaking to Selindile and advised that Selindile would call me back. That was 2 hours ago and no call back as yet. I'm currently waiting on the line for Selindile, its been 34 minuets 24 seconds I'm still waiting........ I'm being billed on my upgraded package already and still no phone. I think its best that I cancel my upgrade and contract with MTN because this is not service. Please can someone call me to assist with cancelling my upgrade, I don't see why I should pay for a product I don't have ....... Looking forward to hearing from you
