Do a search for "Shrockworks LLC" on Google and look at the LLC records. The company status is listed as "Forfeited Existence" With a dissolution date of 19 October 2018. That doesn't look good.
I saw a comment on a facebook post after doing a search for "Shrockworks" the comment said that when that person had been able to actually get someone on the phone back in december, they were told one of the staff members died and they were trying to work things out. Okay, in my opinion, that is understandable, and most customers would understand that, and be willing to work with them... However, when you just stop answering calls and emails, and abruptly shut down your website with no explanation, that does not bode well.
I really hope that any of you with outstanding orders can either get what you paid for, or get your money back.
