H4 EAD Card not delivered even after Change of address


Applied for EAD on April 9, 2021. Vermont service center
Changed address, submitted AR-11 w/ 10 days of move ( August 12 )
No confirmation of address change received, submitted another AR-11 form ( September 5 )
Case approved around September 27
New card produced and sent over to Old address and not New address
USPS confirmed that the mail was sent back to the originating address, which means it got sent back to USCIS

USCIS customer care is not working. It is now fully automated w/o any route to real person. Any input on how else can we reach out to USCIS on this matter.

Any luck with USCIS?
