Post Office and Customs Poor Service!

Wow! Does anyone have the same problem with international deliveries where neither Customs or the Post Office can’t track or find my package? The package was shipped start of November and I’m aware of the Customs duties and that it takes time, but 3 months is ridiculous! Wouldn't you agree? I really can’t believe that a person can struggle with international orders and deliveries So much! I am Extremely unhappy about the service, or lack thereof and also because I am not getting anywhere with this investigation. I have checked with my local post office, but they weren’t very helpful, in fact, they didn’t want to help me at all. They refused to help me. It is so disappointing that no one at the post office is willing to help me. What has happened to the service?? I am not getting anywhere.

Any suggestions?
