ShopGoodwill review: Online auction

I bid on item and win. PayPal transaction completed on Jan 24 th 2019. I check my card it did go thru. They are refusing to mark item paid and ship it saying it's not paid. I sent copy of paid receipt. I open 3 tickets which they closed saying it's not them I need to contact. I opened another ticket which received no response as of yet. I I have been trying to call others numbers I found online but no response. I find it hard to belt that they do not have direct contact to anyone about payment. I am getting the run around and now wondering what's going on. Shopgoodwill had been paid for my item. So where is it or who has it? No. One there seems to know what going on.
