Called and said I had filled out an online survey of some sort. I told them not to call me again and blocked the number.

These people called twice. They insist they are not trying to sell anything. When I asked them how they can save me money, they said thank you and hung up on me.

They call about twice a week. They leave no messages, nor answer when called.

They call my cell phone periodically. They also call the house phone number also. Both phone numbers have been on the DO NOT CALL Registry for quite a while. Well when someone answers, they just hang up, and other times, no one answers. The message used to have an option to remove your number from the list. But I still get the calls. I don't know what phone number the call came from on other occasions.
