I cannot connect my paypal to my bank account. It says it has been linked to an account already but idk which one. I find it very weird and surprising. I have tested all the email accounts I know are mine, to see if I had registered an paypal account using that email but none work, so that is very confusing.
I tried to use paypal about a year ago to buy something but it failed horribly, and I haven't touched it since.
You need to contact customer services to resolve any account specific issues. Click help / contact bottom left of Paypal pages for options available for your country.
Or have you considered contacting Customer Service via Facebook or Twitter? You can send them a personal message from their facebook or twitter pages. It's: https://www.facebook.com/PayPal and @AskPayPal for Twitter.
