I had to take a day of work to get a package from a delivery service - How in the WORLD is that easier than just posting it? What possible benefit did that add?

I had to take a day of work to get a package from a delivery service - How in the WORLD is that easier than just posting it? What possible benefit did that add? Then, it turns out they "Can only estimate to about 2 days", so when the guy didn't show I had to take a SECOND day off work. Then, when he couldn't find the buzzer I was told I had to drive to the warehouse (1 hour away, only accessible by car off a highway, which I don't have) or it would be sent back overseas. I have never used a service as bad or as useless as UPS. It boggles my mind that they even exist.
