Vintage Auto Works?

does anybody know anything about them? i won a bid on an upper control arm last week. they don't accept paypal so i indicated on info that i would pay them by credit card over the phone.i've tried since last thursday numerous times to call them but get no answer not even an answering machine. i'm afraid to send them a cashier's check if there is no communication. i've also tried contacting them through ebay and this morning i emailed them directly. are they out of town? what would you do?
 
still have not heard from them! if no communication by tomorrow i'm giving them bad feedback and going to file for a retract of the bid where i can shop elsewhere for my upper control arm that i need soon.
