I accidentally sent money through paypal on a website

[Stell]

I was on a website and was trying to order a virtual item i thought it didnt work so i got it again but on the website it said paypal was down and now i want to cancel the order but i checked my citi bank app and it already charged the money from me the transaction is green but nothing is showing up on my paypal activity so i cant request a refund from the seller what do i do if he authorizes it and i wont get the items since they arent accepting paypal due to an issue and once that issue is done arent they gonna take it

please what do i do i need the refund but paypal is already trying to take it from my bank account its 78$ but i cant allow 78$ through because i never got the items nor are they accepting paypal what if i request a refund but he says no????
