I most recently ordered a exhaust system for my car, box it pretty hefty size and UPS delivered it to my front door, although I never signed for it it was just left out front and picture of delivery was taken. Can I DNA this? I emailed Summit and they provided proof saying it was delivered and provided picture as proof of delivery. I ordered through paypal . What should I do?

Ask for your signature, they have to justify that the order has been delivered to you.
If the company refuses try to escalate the case.
Paypal dispute should be opened if they refuse to escalate the case, just keep in mind to give all details to PayPal including the email they refuse to escalate the case and their proof of delivery isn't valid because there isn't a signature.

so you're saying that because there's no signature, the tracking saying 'delivered' isn't a valid point for pp to turn down your claim?
