Don't even waste your time attempting to deal with PayPus....
Go straight to your credit card company and charge back through them. They willl claim the dosh back from PayPus and PayPus will take it back from the seller ALL without you having to jump through 200 hoops and waste extraordinary amounts of time with PayPus.
If you attempt to do the same thing via PayPus you will be screaming and tearing hair out sooner than you think.
What conditions must be met for your credit card company to do this for you? Surely they must have "hoops" as well? How is Homepin coming along?
"I paid for goods, but did not receive them" - what happens next is up to your CC company. Some will just record your conversation and need you to state what you did so far with regards to contacting the seller. Some may want you to fill in some paperwork.
Don't fill them in with Paypal junk - as they may want you to follow the Paypal dispute process first. If you do, it will be almost certain that the credit card company expiration for reversal will pass before Paypal get you your money (minus fees) back.
Just remember this: Paypal lost a lawsuit in the US years ago because they were representing themselves as a banking system. They most certainly are not - which sadly means all their promises of protection and happy fuzzy bunnies is not required by law to be upheld - they have contractual clauses that can be summed up as "if we don't fell we have to, we won't pay you back". If you have a banking issue - which this is, it is a charge to your CC for non-delivery, deal with your bank, and let them deal with paypal.
Paypal is a necessary evil unfortunately - until something more altruistic comes along. Auctionchex seems a good idea, but is so damn sloooow...
