If no disputes are opened in 180 days then normally you are allowed to withdraw the funds. That is as long as you are over 18, the account is in your legal name and registered in the country where you reside.
Paypal also may request further documentation from you before you can withdraw those funds.
May be too late now but contact options for Paypal are accessed by clicking help/contact bottom left of Paypal pages...
1. Paypal phones are slowly re-opening and increasing in numbers (you can use the guest option if you can't log in). 2. Live chat is also randomly available. 3. You can send them a message, during business hours you may also be able to message whilst logged out. Or 4. 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.
