This car just sold for $522 dollars on EBay

My paypal account is currently suspended over a dispute, cause a seller sent me a devise he said would work and did not. I was not made 100% whole. paypal deducted 3-4$ out of my account and informed me I lost my dispute.
Are they charging a transaction charge whether or not a wrong product is sent?
I cant find anything. I contacted my CC company, informed them of the deal and they said they would take care of it for me. It`s the principle of the thing. PP contacted me saying they`ve discovered suspicious activity on my account and suspended it. CC company doing their thing evidently.
