MTN S9+ PROMO - GEAR FIT2 PRO WATCH NOT DELIVERED AS PROMISED

I upgraded my contract in August 2018 with the S9+ PROMO - GEAR FIT2 PRO WATCH. I have been constantly using the support chat service to try get updates. I was initially advised it will be delivered between 1 to 4 weeks to deliver the product however it is now going into the sixth week. My last few message I have sent I have not received any response at all. My last response was I got was "We have escalated the delay with the courier......" and that was on the 25th of September and nothing after that. Can someone sort this out ASAP and advise when my gear fit2 pro watch will be delivered this week
