Yes, BE&A are a PG distributor. So's Van's Auto. That solves the "rotten, fraudulent, dismissive treatment of customers and their money" problem of buying directly from PG, but it doesn't solve the lousy part quality.

Send them an e-mail with the Paypal transaction number. Once they see that they can`t deny receiving payment.
They can and probably will behave as though they never received the e-mail, just like they're behaving as though they never received the payment. Ignore the customer, don't return phone calls or e-mails, claim not to have been paid...not going to move the ball down the field. Just contact PayPal and file a dispute. Few mouse and key clicks will do it. Then if PG doesn't cough up the parts or they're of garbage quality, you can easily escalate the PayPal dispute to a claim; PayPal will refund your money and take it outta PG.
