Contacting PayPal does not help when transaction is over 45 days old or You did not paid for goods or services. And there are many cheaters around, not only from Poland or Eastern Europe. My last 2 losses are from Germany - one seller did not sent item at all and another sent defect item. Both are with German names and even good feedback (they are not from this forum). So these things happen all the time. One of my biggest losses is for example with German firm still in business (europe- militaria.com - Hauptseite) - loss over 600 euro.
