Speed keeps dropping

Fibre was recently installed in our area. After some research and reviews we chose Supersonic as it was highly rated for SA. Boy what a mistake!!!!! Speed keeps dropping. Have a 10 mbps line, speed tests show very low speeds most times even saying "Connected: No Internet". We have only been with them since 30 March, and are having more issues then with our previous broadband ISP. EVERY SECOND DAY I need to phone the call centre for them to reboot it on then side, It then works for a few hours but starts slowing down again by the being of the second day it won't even open something simple like FB or GOOGLE.

Every time you phone, the tech has a different story, from it not being activiated, to a router problem, to having too many device connected (which was never a issue before as we're a small family of 4 and previously only had a 4mbps line), more issues now with 10mbps fibre than 4 mpbs broadband. Now they're insisting I upgrade to a 20 mbps line. It seems all they want is to get more money from you, without EVER sorting out the issue.

I would not recommend them to anyone, fibre is supposed to be much better than broadband!
