Test rescheduled 4 hours earlier and remote?

I literally just received an email that says my test was rescheduled from 2:30PM, in a test center to 10:45AM remote. I don’t even have a webcam. That’s why I scheduled in person. Tried to call prometric and they hung up on me and said they would call me back? Mind you the test is TOMORROW and I got this email at 10PM MST.
