Issues with UPS packages in/around Denver

Has anyone else had issues with UPS delivering packages in Denver/surrounding areas? I used Pirate ship to pay for/print labels. Out of around 20 packages I sent, 4 have not made it to the recipient. And all of them were for Denver (1 was Golden but it arrived after 11 days). I sent packages to Florida and New York and those made it within 3 days. But the Denver ones either took almost 2 weeks or still have not made it.

When I look up the tracking, it shows that it hasn’t even been dropped off at UPS, but I dropped them off and was given a receipt with each packages tracking number after they were scanned, weighed, and marked as paid. When I called the UPS store they told me they did not have my packages anymore and did not know why the tracking shows it hasn’t been dropped off—basically there is nothing they can do for me.

This was for a Valentine’s Day earring collection I did and now 4 people did not receive them in time.

I even sent one to Colorado Springs and it arrived in 4 days, it’s only Denver that has had an issue with delivery.
