E-Bay in conjunction with PayPal Ordered health product from E-bay, seller cancelled after I paid on credit card, E-bay promised to refund, but PayPal will only refund a portion USA

I ordered a health product from E-Bay and my credit card was charged.  I received a notice from PayPal that the seller cancelled my order (for some unknown reason) and e-bay told me they would refund the $11.77 through PayPal.  When you go to PayPal, they tell you that they can credit your credit card (which it refused to do in stating that my credit card would not take the credit, which they do on anything else), so I would have to get a mailed check to me, or I would have to send them a copy of my check from my bank account.  Because I do not need a partner to my money, I told them to send a check, and PayPal said it would cost me $1.50 to get the check!

I never cancelled anything, and my credit card will take credits.  This is a scam between E-Bay and PayPal, and I will not purchase anything from either one again.  There is no way that I should not get the full amount charged to my card in a sale that I never cancelled, the seller did.
