we were working fine...

we were working fine on our email Monday morning, with the power outage everything has ben restored besides our emails, we have been logging calls with bitco and they seem to not resolve the issue but push it back into our court, Our IT has logged onto our system to check if the fault is at our office, and he said no, I even went as far as calling our domain host 1Grid and they done a few checks and lead back to bitco, all tickets logged with their support keeps on being closed on their side, if its one company with bad service its BITCO.
