My question involves a consumer law issue in the State of: Texas

I sold a PC video card on eBay to another individual in Texas. He paid via Paypal, funding the payment with a credit card. He subsequently disputed the payment, claiming he didn't recognize my name on his credit card bill. I not only was charged back for the sale, but also a $10 fee apparently tacked on by his credit card company. He claimed he had contacted his card company to make this right, but it's been a long time and now he no longer responds to my emails asking for update. Do I have any recourse? I realize it was a small amount - $45 - but it's the principal as well as the fact that I could use the money that is due me. Thanks in advance for any advice.
