Dropping RFE off at local lockbox

[10pmStalker 6]

I had my interview on February 18. I was told I would be approved after I send in my long form birth certificate and should have my GC within 2 weeks after they receive it.

I ordered one from Canada and sent in a copy, no response so I sent another one Certified mail, took a few tries to get accepted but they finally received it.

I still haven't heard anything from uscis. It wasn't being accepted to the address that was on the return paper so I called usps and had them add Floor 2 since that's the floor my interview was on. Also put the Field Office Director's name on it. I don't know if this caused confusion and maybe it's sitting in a pile not being looked at?

The RFE said I have 87 days to mail it back. I'm worried they won't see it and deny the whole process.

I am now thinking about putting it in the lockbox in person but I have no idea how to address the envelope. I was told it's really important how it's addressed if it's put in the lockbox. I don't know my interviewers name. Should I put my name on it with my A number maybe?
