wierd situation for me

Well as some of you know I bought a crt .5 (used) set up for brushless but still has all the nitro stuff with it including the engine...anyway I paid the guy with paypal $170 and he said he shipped it on monday the 6th of this month parcel post which supposed to take 2-9 business days.....well we had a labor day which I think makes monday the 20th the 9th day....I have never lost anything in the mail......parcel post says theres no way to track this package

my question is do I have any recourse with paypal or usps?...or anyone with any experience here?...am I just sol?

oh buy the way it was shipped from chino hills California to my city Jupiter FL
