Answer the call, The lady just talk with bullet speed to congratulate me win the draw of possible reduction of my energy bill. After I told her that I am not the bill payer and please take my number off the calling list, She just hang up. How rude she is?! If you are looking for a chance of business, Then a "thank you" "sorry" will go a long way. I block this number and now report this number. That's their lost.
