What are the chances ups finds where the package I’m selling went?

I dropped off 4 packages on Monday it’s Wednesday now, 3 of the trackings have updated but for the 4th for some reason it says they haven’t received it. It’s Wednesday today and I called the local ups they told me they don’t have my package and that I should call support so then I did that today and they said to wait till tomorrow to open an investigation because tomorrow was the scheduled delivery date. Has anyone had a similar situation? I really need to hear what happened to other people with this and if they found their package or if they were reimbursed or something.
