EBay question?!?????!?

[Juan Melchor]

I bought some headphones for 175$ and I ha a 15 day money back. I was not pleased and messaged the buyer countless times and he didn't reply until I opened a case. After the case he gave me a return address and said he would refund me right away so I sent the headphones back and he went back to ignoring me until I got his phone number and finally contacted him and he has been stalling me for about 1 month and a half. And he said he will refund me the money the 1st or 2nd but that never came and I've been texting him but he's been reading and ignoring all my texts. I really need the money for school. I contacted PayPal a month ago and they told me to wait it out. What should I do?
