Sorry to be quoting something 2 weeks old, but I wanted to come back to give details about what happened in my case.
This morning, I got an email from PayPal telling me they had resolved the dispute in the buyer's favour and I would therefore lose my £179.95 as well as pay a £14 fee for there being a chargeback and the case was now closed! Needless to say, I was f**king livid. I had supplied all the proof of delivery they needed to show I was covered with Seller Protection and explained how I had an eBay message that confirmed to me which postcode to use from the two that had been entered as the PayPal delivery address. I think some moron must have handled it because the status details were set to:
We have reviewed the case. Because you have not met Seller Protection performance requirements, the transaction will be reversed. The case is now closed."
I phoned them up (freephone number) and thankfully it was a competent human being on the end (Gary was his name) who listened to all the details and said that I should be protected and he would escalate it. That was about 6 hours ago. I just got another email from PayPal telling me I was being given back the £179.95 and the £14 chargeback fee. It now shows up my account as a transfer from "PayPal Balance Adjustment". Thank you, Gary at PayPal!
So it basically all worked out in the end. Phew! I can't afford to be down £200 right now.
