So I got a new visa card with around 40 dollars on it and when I try to confirm my card it says "Your card was declined by the issuing bank. Please try a different card or contact your card issuer with questions." please help!
As you have not added your country to your profile (so we can see when we hover over your username) or said in your post which country you are in then sadly can't advise. Paypal varies a great deal country to country so you need to tell us where you are on this worldwide community forum.
Advice is voluntary. Kudos / Solution appreciated.
