Support doesn’t typically respond on the weekends, and their turnaround is quoted at 3 business days. As jb mentions, creating multiple support tickets will slow the already slow process down even further. It’s a bummer that your machine isn’t working, but patience is going to be your best friend on this. To set expectations, I’ve waited for over a week for a response, while others have gotten faster responses, the last few months have seen an increase in users and support tickets. If your machine needs to be replaced, and you are still within the warranty window, they may offer you a refurbished unit (I just got one that was pristine and had I not known it was a refurb, I would have guessed it was new) or they may offer you a new one, which typically takes longer to get out than a refurbished machine. Hang tight just a little bit longer, and I’m sure they’ll get you taken care of.
I’d suggest not creating another post in Problems and Support again, and if you’ve emailed them they will continue the discussion over email, or may close every post in here and continue the discussion over email regardless.
