You are only allowed 1 dispute per transaction so the only way you can get a second dispute opened is to contact Paypal (when and if you can) and see if they will open a second dispute for you.
They may decline citing policies but if you say you made a mistake then they might open a second dispute for you.
If not then if you funded your paypal payment via a credit card then consider contacting your card issuer and see if they will help you with a chargeback?
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.
