Refunded Paypal Credit payment still showing as unpaid after 3 months
I purchased something on 10 of May on PayPal credit. I cancelled it same day as I changed my mind. Shop refunded full amount the next day. I logged in to my account to check something and I found out that there is still full outstanding balance showed on my paypal credit for this payment and it still counts towards my entire paypal credit balance. Can someone help ?
