Device Deliver Syspended - No Resolution

I am getting highly irritated with MTN and RTT Couriers who are meant to have delivered my new LTE Modem after an upgrade which was done last week Monday 2 November 2015.<br> <br> RTT tells me they have the package with them, but MTN has suspended deliveries.<br> <br> I have called MTN every single day since and requested that they rectify the situation. Every day I get promised prompt resolution, but typically nothing happens.<br> <br> 2 days ago when I phoned, I was assued that the issue was being attended to and was promised a phone call from the supervisor, my details were taken but needless to say noting has been done and of course the phone call never happened.<br> <br> Now it dosen't even seem possible to get through to these people on the phone.<br> <br> I EXPECT a call from someone explaining what is going on, I EXEPCT this issue to be sorted out pronto, and I EXPECT to see a credit on my november invoice for the days I have been left without service as I have no device!
