Account Warehouse Accountwarehouse Did not receive promised payment, Internet

I recently sold my US Wow Account along with Diablo 3, I was promised $60 for this account.  After giving my information they took the account, and now I should have the money.  I was sent 1 cent to my paypal account and I haven't heard from them since, even after sending several emails.  When I try to call the "Customer Service Phone: 806-445-3771"  no one picks up and it sounds like someone's personal cell phone, "this person has not set up a voice mail box."  This looks like a scam to me.
