I have a few of the WIX UOA kits I bought off of Amazon on a deal some time ago and figured it was time for our Armada's yearly UOA on its last OCI. I sent it on the 1st as well as another package for work both first class with tracking. I knew my work item had been delivered so I decided to see where my oil sample was. Tracking showed it left for the sorting facility on 3/1 and that's it. I then called USPS to open up a case with them. They said it could take up to three days for someone to call me back. I was surprised that someone from USPS's destination post office in Ohio called me this afternoon. It was her response that was disappointing. "Well, we will keep looking for it". Um no. You need to light a fire under someone to go find it. That is why I have tracking on it. It never left Indiana. Why in the world is the destination post office calling me? I paid the post office money to take my package and deliver it to its destination. Tracking says it never left Indiana, so why look in Ohio. Tracking shows it left the facility and went to sorting and hasn't left. Why aren't they following their own tracking?! You know, it's no wonder FedEx and UPS can survive and be successful with USPS as their competition. Next time I am not even going to bother with USPS. I have heard on here of them losing samples and now it has happened to me. This will be a news story when it gets delivered in 20 years.
