Called them and left a message on a Thursday about a month ago. I also emailed the same day using their website form, indicating the specific issues I was having (model, OS, RAM, etc.). The next day I got a return call from their admin saying only that someone would come to my house and it would cost $140 ($150?) for an hour. Told her I had emailed with the specifics, and I asked to speak with a technical person for a few minutes first, to get their view on my issues, whether they could solve it, and if so, how long it might take. She assured me I would be contacted. I received no reply to my email and no call.
