Order cancelled for no reason

I placed an order for a landline on the 25th of March 2019. I continued to track the status of my order for the weeks that followed. Yesterday, I received a call stating that the order that I had been waiting for a 3 weeks needed to be cancelled due to a technical glitch. This is after I called the client centre numerous times being told that the system is offline. I was subsequently told that a new order had been placed and I would get an appointment with a technician today. This never happened. I was not given a tracking number or any way of following up on this. I called client care again today and after putting me on hold for 42mins, I hang up! Promises, promises promises that are never kept. Pathetic!
