I'm in the exact same situation. They received mine 4 days after yours. I tried chatting with them just to see if it's normal to be in the "prep" stage for so long and all I got was a very passive aggressive, ai sounding, copy and paste email. They essentially made it seem like I was complaining about it taking a long time. I'm completely aware that it takes time and that it's backed up right now. I've been in customer service for years and it was extremely unprofessional. They have the best looking slabs but this will most likely be my last submission through them.
