According to my experience. If the dispute is not responded for a long time, firstly you should contact the seller to return your money. if no feedback from seller In addition, you can also contact paypal using Help> Help Center> Masage Center. Ask your problem to paypal customer service.
Usually it takes a process of 5 days to 10 days, if the evidence is complete then the case will be won by you.
I hope you able to receive your refund soon
