No Delivery

Hello, I have been waiting for my international parcel since the 8th of January and have had no success in trying to locate it here. I have emailed customer services for a few weeks now and every time get told they can't see anything on their system which leads me to believe that my parcel is missing and that is not what I want to keep thinking. My tracking # is LN***5US. I would greatly appreciate it if someone could help me as customer services email keeps telling me the same thing.
