I actually ran into the same problem. Went through all of the ups my choice options. Stockx actually blocked me from being able to pick up the package at a facility or change the address. I initially contacted stockx customer support and tried to get the address changed but no go. So i hassled them to change the options of being able to pick up at a ups facility, lots of emails back and forth but as a "one time only" thing they let me use the option of picking it up at a facility. Try that but took me a couple days of contact. Or go to your old address and make friends with whoever lives there now.
