harrassing calls

This company keeps calling and when we say we dont need service they tell us that is probably because we have no money and worst.  Does anyone have a phone number to the company I tried calling one i saw and it goes to a therapist number.  I want to file with BBB.  I am a senior citizen i dont need this harrasement several times a day. The number they called from today is 949-5724454, the number is never the same and they wouldnt give me there corporate office or address or manager name so i can get my number off there list.  How do they think they can get business this way?
