Supersonic don't get it at all

I was actually referred by someone to join Supersonic due to my previous bad experience. But i don't know what happened, since inception i had issues: - On installation i was not advised that the unit (router) can take up to a week to be installed. lucky i still had my previous provider, mmm sorry Supersonic removed my previous providers line when they installed there line... so i was *****ed and had to fight, was without internet for 2 days. -They stipulated that the network is not being throttled, but constantly in the afternoons my speed dropped to under 10mbps. I have all the constant massages. - I have been with them just for 2 months and already my router is not conflicting, and now they tell me sorry but no solution and it is stipulated that it takes 48 hours to be fixed. so again without internet and i am losing out on business. The staff as well has this i don't care attitude, it is your problem, what happened to be proud of your product, what happened to good service. I think the best is to cancel the contract.
