Change in Signal Coverage - Kensington, JHB

I have a WAKA7 mobile device that I have been using for since March 2016 at my residence in Kensington, Johannesburg and I have pay subscription fees up to and including June 2016. I were viewing the rugby matches on Saturday, 16th March 2016 with no signal problems.<br> Since Monday, 18th March 2016 I can no longer view anything as I now have no signal coverage in my area, no matter what I try - resetting my device manually or on-line.<br> Calling the service desk was most frustrating as they only pointed out that there were nothing that they can do as there are no signal coverage.<br> I have received no notification of any change in service/signal provision from either Multichoice or DStv and utterly no help from the service desk.
