eBay

So I bought something from eBay for around $100 and it was due to arrive from 18th October to 13 November. I got it today lmao. And on the site, it still says "In transit". If I don't say anything and wait till the delivery time is off, should I say that it has not arrived? Or the tracking info will change to delivered in a few days.

From experience it takes some time to update. I once had a package delivered to me , and didn't get a deliveryman confirmed email 4 days later yeah it'll update eventually

What carrier? it depends. And there's a slim chance that you could win that "never arrived" claim in eBay, as long as the seller provided a trackable tracking details, then seller is 90% will win the case.
