Custom clearance ISSUE

This company deserves no review at all, this is not the first time I'm experiencing a problem with them. If it's not being charged a lot of customs duties then it's them holding my package for over a month with no explanation provided but "just customs clearance procedure". This is absolutely frustrating because some of us make money through the package that is shipped to us, they keep on postponing the day I will receive the package and even ignore my emails and when I call, they keep on telling me different time periods the "customs" will respond. I am extremely drained and tired of calling and emailing without no respond, mind you calling costs me a lot of money as I will be put on hold for more than 10mins. UPS really needs to shut down because they fail to deliver and their customer service is very bad. Can you just deliver my package which you held for more than a month now, I really do need the package as I make a living through it.
