This stupid company always calls me and says my car warranty has expired and I should immediately sign a new contract... When I tell them I do not have a car they immediately hang up...

This number has somehow found my cell number. So I stay on the line to talk to a rep and ask to be removed from their database. They just hang up on me! Yuggh - what a nuisance- but when I travel overseas I incur costs for their stupid calls. What can I do about it?
