Thried Several times to call about Energy Services

This compay Vitelity, LLC (on Caller Id) calls and claims to be Santana Industries.  What to Talk about Energy Stuff..  They have been trying for over 2 weeks, by calling with hang-ups and then finally with a local Telephone number(I believe it is a Cell) I have told them to take my name and phone number off their list and nothing has happened yet.  I am sure this is a scam......
