Best course of action to get eBay refund for non-delivery?
I ordered something on eBay. Fedex says they delivered it, but I never received the package. I requested either a refund or another shipment from the seller. I don't know if Fedex delivered to the wrong address, or if the package was stolen. All I can say is that I was home and Fedex didn't ring my doorbell. I went downstairs to get my regular mail 2 hours after the alleged delivery time, and the package was not there.
If seller refuses to issue a refund, is it better to try to collect under eBay's money back guarantee, or should I instead file a credit card dispute? Ebay's policy says that if I attempt to collect under their option, I have to accept their decision as final. From what I've read on the website and elsewhere, it seems like eBay could reject my claim because Fedex says that they delivered it. I called eBay and spoke to someone, and she told me that I should be able to get a refund if they step in. But I'm not sure that she knew what she was talking about.
What happens if I file a claim with eBay, they reject it, and I file a credit card dispute anyway? Is that definitely against the rules? If so, what is the penalty?
To clarify, it was a box of 600 empty ink cartridges for $42,95. For eBay's dispute resolution, it says that a signature is required if the item is at least $750. Perhaps if I can't get satisfaction from eBay or my credit card, I can sue Fedex in small claims court. It is really their fault.
