Personally, and this may just be me but with so many other customers having problems and little to no contact from the administration you wouldn't find me anywhere near that host.
IMO you should move asap.
Well, i was going to move immediately, but with no issues to my hosting since, ive kepy it there, save paying for new hosting. Thaough ive been keeping a full backup each week unless there were issues, then i could move hosts in a day as my domain isnt with SS.
I'm in the process of researching hosts atm, and will most likely move during the next couple of weeks
