How to file a chargeback through paypal?

[spydrman]

I have a friend who bought something on e-bay using Paypal e-check. It's been a lil over 2 weeks and the seller isn't responding. I told her she should file a chargeback. I'm not sure how to do this, is there a simple way?

I found a Buyer Complaint Form on paypal's site under help...
