Called but I did not answer and then blocked them. If their not in your contacts don't answer. If they want you bad enough they'll leave a message. This works for me.
Unwanted, unsolicited "boiler room" telemarketing call - Solar Panel sales. Even if it were a legitimate operation, why would I ever do business with any company that knowingly violates US Law by not complying with the DNC law/list? Simple answer... no way! Now blocked.
