Green card delivered to wrong address.

[locutorio]

USPS delivered my green card to my old address! They didn't even bother to confirm I was living there.
The status of my card is delivered.
I updated my address with USCIS before they produced the green card. It's their error.
Anyways, I phoned the guys living at my old address, and asked them to return the letter to the post office.
What's going to happen now when USCIS receives my card back?
I phoned 1-800-375-5283, the operator cannot give me any personal information by phone, so she cannot confirm the address on file. The only advice she gave me is to make an appointment in person.
Is there a way to tell USCIS to send the green card to my new address by phone?

How do you know. it is delivered to wrong address. And also how long it took for them to mail the Green card after entry in USA

Did you do a general change of address AND one for a specific case number?

You should have gotten from the new tenants. It would be so much easier...
