I am on the same boat as you, I was getting some response to my email after 2 days, but then there is no resolution on how to schedule my turn yet. If you have an appointment scheduled already, it shows a Reschedule button, but if you it is canceled there is no button available to schedule our turns. That’s the case for us.
My receipt has expired on Oct 9, and I have been trying to get a resolution since Sep. It is really frustrating.
