They have my direct phone number at work and call multiple times daily. I have answered the call many times and no one will speak. I have decided to answer each time they call and just immediately place the call on hold. It's amazing how much quicker they hang up when they get put on hold! It's annoying but I can't register the business number on the Do Not Call Registry list so it's what I have to do in order to keep smiling through the frustration. Jerks! :-O
