Appalling service from Mweb and courier partner Dawning

Mweb's service is shocking. They advertise their product, get prospective customers to sign up, and they simply abandon them after that, or shall I say the hand them over to a courier company , Dawning whose service is equally appalling. I called Mweb to cancel my order last week, and the lady that I spoke to pleaded with me not to do that, saying that she would escalate the matter to management. Did I get a call from her or her management? Yes you guessed right, not at all. When I tried to call their "Head Office" number, I am directed to their call centre number which has long waiting times. The order tracking on Mweb's website is very confusing or shall I sat misleading e.g. "waiting for instalation" when they have not even delivered the router, and they do not have the correct email address. Maybe it is not a bad thing that Mweb has shown me early what type of service I should expect in what I though would be a long an mutually beneficial relationship. It is a pity that the minimum that I could rate them on this portal is one star, otherwise I could have given them a zero rating. About Dawning, they promised to deliver my router last week, but they did not do that. I get a missed call, and two calls after that which I answer, only to have silence on the other sides on both occasions. I call the number back and I made to wait on the queue for +/- 15 minutes. When I eventually get through a person, she transfers me back to the queue, without explaining where she was transferring me too, and without checking if I was prepared to be transferred
