I worked for a company as an administrative assistant. When they decided to get ADT security system, I gave them my cell phone number as a contact for when they were coming to install. Long story short, the company went south, I got laid off, and they never paid their bill.

Now ADT calls me EVERY DAY. Sometimes 3 or 4 times a day. Even though I have told them I made no business decisions for the company, they still won't stop calling me.

Is there anything I can do?
