Pretty much the same scenario as "Jim" describes. Numerous calls. If you wait for the prompt and immediately ask for their name, they hang up. Then, I made an appointment. The guy showed up on the wrong day and put his boss on the phone. They spoke in what sounded like Hebrew to me, so I assume they are Israelis.
I am getting tired of these calls. They call to sell their carpet cleaning service. I asked several times to be removed. They call twice as much since then.
