Buyer Beware/Trac Dynamics

Long story short I sent a bank check to this Calif. shop for a swing arm for my 01 Lowrider. The check was cashed 8/20 and an agreement for a 3 week turnaround. Still have no swingarm and they don't answer they're phones or return emails. A message claims they're moving but does not give a new location. It looks like they're having a fire sale on their website. Looks like I'm going to get corn holed for $1,100.00 I have everything documented
