If purchased online, contact seller & ask them to contact USPS.
An item I'd ordered from Amazon was supposedly delivered, but was not in my mailbox as stated.
I called my local USPS & got the typical fuck you consumer attitude this region is famous for.
Then I called Amazon & shared my concern & frustration.
Within about 15 min, my local USPS facility called me to apologize & assure me they had sent my mail carrier out to check every mailbox on my street. Of course, I thanked them & went outside to see if they were being honest.
Yup. Mail person was checking every box & pulled it out of a.neighbor's mailbox, brought it to me & half-ass apologized.
So, whenever something you order goes amiss, pray to the almighty corporate gods to intervene because that's the only was I got action.
Last fall, well before Thanksgiving. grandson sent off an auto oil sample for analysis (who knew such services existed?).
The small package destination was only about 150 miles away.
Now fast forward to about February... and we were still being told "we're still trying to catch up wifh holiday mail..." i asked her "Which holiday? Valentine's day?" Her answer: "Oh no. Christmas."
This is a typical excuse used in many businesses in this red shithole.
Anyway, the package finally arrived safely at the testing lab months after it was sent.
So now, after typing all this, I realize since you paid the postage, you must've mailed it yourself, making all this a moot point.
But I've decided to post it anyway because it could be helpful to others.
Good luck!
