Parsons Pest Management Walter Parsons, Recieved PayPal payment but did not ship complete order. Won't return phone calls or e-mail. Internet, Texas

I ordered two (2) items from Parsons Pest Management or Control early January 2012. They received payment from PayPal, 1/14/2012. One of the items was shipped sometime later and I was told the other item was on backorder. They couldn't provide me with an estimated shipping date so I cancelled the backorder. A credit was never issued for the cost of this item or the freight they charged for it. Made several phone calls and sent e-mails, to no avail. Tried a dispute with PayPal and that didn't work either. I guess I'm out the $40.00 bucks, but they haven't heard the last of me.
