Has been calling multiple times a day! A noxious!

This company and or phone number calls multiple times daily, sometimes without answering and then hanging up. Every day I ask not to be removed from their calling list. Each person who has called barely speaks English. I'm looking for the next step if anyone has any info?

CORRECTION*** I ask to be removed from the calling list****

They asked about my 2009 JEEP. I said I no longer have that vehicle as I really do not.  He asked if I could tell him what I am driving now to update the system. I replied NO.  He he said thank you and hung up.  They claim to be a Vehicle Service/ Warranty related.

They tried selling me a warranty for my 2010 Jeep too, which I no longer have.  Once they heard I no longer own it they tried selling me a warranty for my current 2010 Mustang.  Even though I told them I'm not interested they still continue to call on a weekly basis.
