We used to get about 6 calls a day from creditors looking for the guy who had the number befor we got it. We would tell them over and over again that he no longer has that number but they continued to call anyway. So one day I told one of them they had reached the Smith Family Mortuary well he apologized and said they would remove my number and hung up. After about 3 weeks they all stopped calling.
I know your situation is slightly different. I've never had a problem with solicitation calls.
