I can't understand why would somebody order something from Google and then use the chat "support" app to ask where their package is. All packages have tracking numbers and as soon as they are "on their way" you just contact the Courier or use their site to track it precisely. Why escalate it to the seller who has no idea where the package actually is?
Because when the courier is Fedex, contacting them would be even more futile than Google.
I also use Project Fi; I also ordered a Pixel3 when it went on sale last month.
Fedex attempted delivery when I wasn't home; I had important meetings the next day and couldn't stay home again, so I used Fedex's "hold for pickup at Fedex Store" feature to re-route the package. This was a crucial mistake.
Fedex then refused to deliver the package to either my house or the store; they sat on the package for TWO WEEKS, all while their "Customer Support" lied to me about what the status was (It will be delivered EOD today; it's already been delivered; it's going to be held for pickup...etc).
In the end the only way to get them to deliver my package was to contact the shipper, Google. It was delivered two days later.
> Why escalate it to the seller who has no idea where the package actually is?
Because shipping is the seller's responsibility. If the courier loses the package, you can't do anything, it's the seller's problem. Only after the package was delivered to you does it become your problem.
