WTBWin me a Paypal dispute

Heya, I do YouTube videos and had a sponsor do an unauthorized chargeback on a $425 payment.

I'd really like to win this, I'll give 10% of the total value via PayPal if won. I've already uploaded 3 of the 5 owed videos as well.

If you think you can help me win it let me know, won't be handing over account info though.

It's a virtual good? Have you said that..Cause it is, Unless I'm mistaken.

Your best bet is to look at the contract between you and your sponsor and make sure neither of you are breaking the ToS you agree on.

If you broke their ToS then they most likely can chargeback anything they owe you without the face of fraudulent, and if they didn't and you are 100% sure just bring that up to Paypal, make sure to escalate the dispute as soon as possible to speed up the process.
My advice, next time make sure you are using a trustworthy sponsor.
