Asked to cancel order, seller isn’t responding and I can’t get help from eBay

Hi,

I ordered some ramen I’ve been desperately searching for that doesn’t seem to be available anymore. I placed this order on 1/30, and the item seemed to sit untouched. I looked at the seller’s account and saw a review that said the item they ordered from the seller never shipped and the seller never responded, so they had to cancel.

I decided it wouldn’t be worth it and put in a cancellation request. It said it could take up to 3 days for a seller response. It has been more than 3 days. If you guessed it, you’re right, still no response.

I just want my refund at this point. But if eBay is waiting on a response from the seller, and they don’t respond, what happens next? What shall I do?
