Packages not being scanned

I dropped off 3 large packages at my local post office on 06/27. They still have not been scanned and show they’re awaiting to receive my package. I called the post office who states they do not scan in any packages, they send them directly to the Ft Worth plant who will scan them in when they receive them. It’s been 4 days and still not a single scan on either package?! I’m not sure what to tell my customers other than they were dropped off but I’m sorry I have no proof! 😭
