Hi "desperate from England,"
I do apologize for your issue and some of the frustrations you may be having with your sites. Do you have a ticket # that I can check on for you so that you do not have to provide all of your information about the issue all over again?
It sounds like what happened is one of your scripts may have gotten exploited because of being out-of-date and this can cause extreme high CPU on the server which our admins usually have to move you to an abuse server until the issue is resolved as to not affect other customers on your shared production server.
I am just speculating the cause as I do not know your primary domain on the account or the tickets referenced, but I will handle your ticket personally if you can provide me with the number
