Refund

I purchased an Item from a store called Straightuppumps on October 1st 2023. My friend recommended me to get their product since it was of high quality. I assumed it would take a month or 2 to get to me, but I was severely wrong. I have tried contacting the seller multiple time with no response. I cannot access the receipt information since he deleted the shopify website of www.straightuppumps.com and I can’t seem to get some help to resolve this issue. Does anyone have any ideas?
