Even if PayPal blocks you, you would still have access to your account (being able to login) but you would be restricted from using it. It sounds to me like you may be a victim of phishing / hack and that your PayPal may be compromised.
I am not saying this is the case, just a hunch - you will have to call them, they will validate your information based on what they have on file, so your legal name, mailing address, date of birth and they may ask you other info, make sure that the info you give matches what they have on file, and NEVER access PayPal from an e-mail link. You do not need to be logged into your account to contact PayPal.
Navigate to this page:
You will get all the information you need, and options to contact them. Do not ever give your information by e-mail - there are MANY PayPal phishing e-mails circulating, only access PayPal through the official site. If your PayPal account was already verified, then it's likely they will only ask you your full name, address, date of birth, they should not be asking any info they don't already have in your account. If you still cannot reach PayPal, you can contacting them through 1-888-221-1161 - Make sure you call using your phone that is registered in your account, do not block your number, the phone number must match. They may or may not ask you other questions at their discretion - you will also likely need to provide them with your login info (e-mail.....)
