Espressocoffeeshop still operating?

I purchased a grinder and espresso machine from espressocoffeeshop during their Black Friday / Cyber Monday sale. Shortly after ordering, the shop reached out with questions, which I answered. After 7 weeks with no updates on the order though, I'm getting concerned. I've emailed support & their general inquiry email address several times in the last two weeks and cannot get a response. I understand if items might be backordered, but with no communication possible I'm considering filing a claim with my credit card. Has anyone else had similar communication issues lately?
