USPS Sent Back My EAD

ok, so on the 1st of November I got a text saying that my case had been updated. looked at my case online and it said that USPS sent something back to USCIS. called USCIS asked them about it, after spending an hr on the phone, the guy sent a request to CSC to have whatever the sent, sent back to me.

on the 2nd on November I got another text saying my case had been updated. again looked online and saw that the circle for my EAD has moved from review to card/document production. I am assuming this means that i was approved. but once again it says that USPS sent it back to USCIS. called AGAIN, and the lady once again sent a request to CSC to have it sent back to me.

so my question is, how long should it take for me to get my card? it's been a week already (5 days, if you're not counting wkends) should I call again to see if the request has been processed? if they have mailed it already?

i'm just sto eager to get my EAD already.

thanks in advanced for any responses.
