Dissappointed with Vumatel and home connect

I am utterly annoyed with the customer service by both Vumatel and home connect.I paid more than a month ago for fibre to be installed. It was a month to month deal and I got no communication after paying. I was only assisted to get payment made. Thereafter my emails have been ignored by both Vumatel and Home connect. They are ever so ready to get you to make payment. But won't assist further. I even asked for a refund. No feedback. I was told my payment doesn't reflect on the system. I'm about to take this to social media and inform people to refrain from using their services.
