I swear, the USPS LOLOL

You are lucky you even got your parcel!
I am waiting here [ Australia ] for a parcel sent from Tenn with USPS. It went to NJ, then Miami......& then tracking said........return to sender! It gets back to Nashville....& tracking now says 'In transit'. Doesn't say where it is in transit to...
You cannot email USPS with an inquiry outside of the USA because it only accepts US address details. Apparently the boffins at USPS do not realise their organisation ships to countries other than the USA....
