SuperSonic Day two No Service or feedback n

Going onto day two with no resolve or updates from anyone at supersonic. Calls get logged and never ever get attended to. Case number or ticket numbers go missing and new ones get issued and we start all over again. I mentioned that the line was faulty and I was asked if I was an engineer LOL ... well she definitely isn't. Average rating of 2.5 and ranked 36th as an ISP and we wonder why??? Or do they even care what there ranking is??? We are forced to use Super Sonic as our Estate has a contract with them. This gives them the right to deliver zero services and continue to bill us as the see fit. Even triple bill and then wait weeks for the refunds.
