Supersonic FLTE

I opted to move from Afrihost (ADSL) to the Uncapped (Black Friday) Uncapped FLTE service from MTN through Supersonic. The process was flawless. I called them to confirm that there was no FUP and the service will run at full speed (unshapped and unthrottled). So I cancelled my ADLS and signed up for the new service. The router/SIM card arrived the next day (Tuesday last week) WOW, I was super impressed. I plugged it in, popped in the SIM card and nothing worked so I called them only to be told I would need to wait 2 to 24 hours. So the next morning I contact them again via Whats app and Messenger (off their Facebook page). Whats apps was a complete waste of time but at least with Messenger I got a responds. first I was told the data allocation was wrong and they would fix it. I kept telling them the router is NOT SEEING THE NETWORK. So 1 day moved to 4. On the Thursday I had a discussion with the tech as I was able to re-instate my ADSL service but he assure me it would be sorted out before Tuesday and I need not worry. Well, we are now at Tuesday and the service is still not working. I have now been told that MTN don't offer LTE service in my area but Megans iPhone runs at 40mb up and down on the MTN LTE network. I think he means FLTE but anyway. So now I my using my Vodacom FLTE backup service with is only 40GB (should last 1 day) and the best part, supersonic are charging me R999 for the privilege of using their service....... I have asked for a manager or supervisor to call me and apparently they have been told of my request but still no calls.
