MTN SUPERSONIC Air Fibre Fail

I ordered an air fibre product from MTN Supersonic and when the technician came to do the installation he found out that the routers he had were faulty. The technician is from Motivity which I assume has been contracted by MTN to do their Supersonic installations. He then said it is a failed installation and has to remove the antenna he had already installed and said they will call me to reschedule the following week. The installation was on a Friday and Monday around 10am I called Motivity on the 2 numbers I have but there was no answer. I called the technician and he said he will ask the office to call me but the call never came. I tried again on Tuesday and still no answer, even the technician didn't answer this time. I contacted Supersonic on WhatsApp and they said they escalated the matter with Motivity, this wans on Monday the 6th December. Om Tuesday I called the MTN call center and was told that they will call me in an hour or 2, 7 hours later I called back and the agent asked me when am I available for an installation and I told him the next day. He said he noted it down and Motivity will call me when they come. On the 8th I contacted Supersonic again on WhatsApp since Motivity did not call me and the agent told me the matter was escalated to the project manager as it was a failed installation. It has been two weeks now and still no communication from Motivity regarding the install. How long does it take to replace a router? Why is Motivity not answering their calls? Why is Motivity not contacting me? Why is MTN so casual about this? Why is MTN not ensuring that Motivity delivers what they are supposed to deliver to a new client? The customer service from both MTN and Motivity is shocking. If I'm struggling with a SIMPLE installation it makes me wonder what would happen when I actually have the product and encounter technical problems. I am disgusted and irritated by the behavior of both companies. Utterly disgusted. If possible I would give this zero stars, it doesn't even deserve 1.
