Wow. This seems like such a change from the previous update you gave us on this. I had thought you were resolving it. It's like they're giving you whiplash with their back and forth run around. Quark and Scott Dunn are definitely on my no list now.
But seriously: if they don't refund you, get your bank involved and on it. They cannot charge you for something they did not provide, and while you may be contractually obligated to forfeit deposit, they most likely cannot legally keep all your money while providing nothing.
Travel contracts don't generally contain clauses saying you lose your money even if the company cancels, as that's ridiculously unfair. However, this pandemic may, unfortunately, change that.
We should all watch the fine print more closely from now on.
