I wanted to link my paypal account to my bank account. But it says that my bank account is already linked to paypal but I have never done that. How is possible. Help me link my bank account to my paypal
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.
