Disgusting service from MTN Direct and DSV

I did an upgrade with MTN via the MTN Direct number in July 2019. By mid August the upgrade had not yet been processed, and when i called i was told that they were unable to open my documents (why i was not called to discuss this i do not know0. I then re-sent and a few days later the request was processed. I was then referred to contact DSV 2 weeks ago to enquire re the delivery of the device. When i called I was told tht they cannot get hold of me (the were trying to call me on the number attached to the device I am waiting for). The entire week last week I called daily to enquire about it, and each time I was told my request to have the call made to my MAIN MTN # is being escalated to MTN and i would have feedback in the next few hours. A week later and this is still not resolved. I have spoken to 3 agents at MTN today, each time with a promise to call back - last call was at 1:53pm - and we wait.... not holding my breathe as I may just pass out from lack of oxygen. 2 months to process and deliver an upgrade - this is beyond shocking service and I am at my wits end and ready to cancel this contract.
