Vumatel bad service

I moved on December 1st and wasn't able to get my WiFi to move with me, had to get a new ISP so I signed up for fibre through Vodacom and could only get Vumatel. Vumatel called to book an installation for Friday December 8th at midday. I get a call at 2:30pm on Friday saying that the technician has an emergency and won't be able to make it, then I'm asked if I can allow installation at 7:30am on Saturday the 9th. I accept this even though it's much too early because I work from home and need my WiFi connected. This morning at 6:51am Chipiwa from Vumatel calls me to tell me he's at my gate for our 7:30 appointment. I didn't complain as again, I need my WiFi connected. He's all done by 7:30 but then tells me that their app is offline so my service will only be activated in 2 hours. All I can do is accept this because what else can I do. He gives me his number and tells me to call him if its still not active in 2 hours, he then leaves. 2 hours later, still no service and I call him, he says he will get back to me but doesn't. A couple of hours later I call him again and he says according to the lady at the office, our service is activated but I tell him that this is untrue. He then says he will call me back, but again he doesn't. At 3pm he calls and asks if it's working and I tell him that it's not, again he says he will call me back. We are now on almost 15 hours with no WiFi after installation and Chipiwa has not called back and Vumatel has not even once tried to contact me to fix the problem. This is atrocious service from Vumatel and I would advise anyone to stay very far away from them.
