Supersonic Fibre

Signed up for a deal but I’m getting the worst experience from customer service. Router was delivered on the 17th of April but was only installed on the 2nd of May. Till today router is not working and I don’t know how many times I’ve called their call centre but issue is still not resolved. Spoke to someone from Supersonic on Facebook and they no longer responding to the chat. Secondly agreed was R279 for the first 3 months but it’s my first month and Invoice came to R401 which was not the agreed and the router is still not working. I’m so disappointed.
