who knows ? what could i do ,for advice

A few days ago, I bought 5 pairs of the new style AJ 2009 from www.ok-jordan.com , where i found the website from this forum .I have left a message to them : “Please,send me the black style one !”,but what I received are two all-black shoes .
What I could do ?
If refund, how can i return , the payment methord I chose is paypal..he paypal prompt：
“The money has been sent!
Josegh, you have sent $196.00 USD to Yi.
We have sent you a receipt for this transaction, and an email has been sent to your recipient. View transaction details “
Could some one give me more details ? Thank you !
