Terrible customer service.

I ordered an installation for the Wi-Fi of vuma which is under MWEB on the 18th of March and made payment on the 25th of March but till now I haven't been installed. Several attempts of contacting them on line, on the app and even on Facebook dm. I don't get any response or even my money. Last time I got a call from them was on the day I made payment and they said they will create a house profile for after first saying they have activated me when I don't even have the Wi-Fi router. I've been sending them messages asking my money to be refunded as I no longer want their service. They keep sending me from pillar to post promising to be in contact.
