I have lodged a few disputes with Paypal and each time the issue was resolved very quickly, sometimes the seller just needs a bit of prompting from Paypal to get things moving. I find that 99.9% of sellers are genuine but occasionally there is a glitch in the system that will cause deliveries to be delayed, like my latest order that was put on a ship instead of an aeroplane, took four months to get here, but at least it arrived.
