Late Delivery and bad customer service

I was supposed to receive a package on the 9th December, no one called the sender to notify them that there are documents that are outstanding for my package to be delivered. I called UPS, 3 customer consultants hung up on me and the 4th gave me a vague answer on when I will receive my package. What upset me is that I paid so much money for this package to be sent here and then I get below standard service from the very people I paid to delivery my package. I would have really appreciated a more detailed explanation on the website telling me that they need my ID number. Telling me documentation is missing and that UPS is resolving it doesn't say anything to me. Because it came through to me as, this is documentation which is totally handled by UPS it has nothing to do with me. So please be specific, your service costs too much for you to not deliver!<br>
