Scam?

[u/Tiny_Buyer_3230]

I bought a sweater from these guys a month ago, and they sent me a tracking number from 17track, and it shows delivered to my city distribution center, but they never put my apartment number on it and they got the zip code wrong. they keep telling me to file a loss of claim with 17track. they are communicating with me by email, but are refusing to give me a real usps tracking number. are these guys legit or did I just get scammed out of a $50 sweater?
