Unless you received confirmation from whp that you will no longer be billed I wouldn't count my chickens so to speak. Webhostplus right now is having many issues (searching wht will show various discussions and outage threads pertaining to them). I'll let those threads speak for themselves. I would definitely suggest contacting your bank and get any charge from them blocked.
WHP has trashed every company that they've bought. Maybe all they want is to sell off the hardware. They certainly seem to go out of their way to drive off the customers. I was with netbunch which had a very nice forum. WHP killed it when most of the posts were about how bad the service was.
