This called us 3 times today, and have previously called our home. They never leave a message. We've had this happen before with an "unavailable" number that called us in this manner daily for months. Once I got fed up and answered the phone. Initially I was greeted by a robot which transferred me to an agent in India. I asked (rather angrily) what company this was. He asked for my mother by name, and I again demanded to know what company he worked for. He refused to tell me. I told him not to call again and hung up. The calls continued for another month or so, but finally stopped. Now we're being bothered yet again. At least this time the number is listed in the caller ID along with "cell phone," so hopefully we can have the call blocked. I wonder how they're getting our number.
