Is there an exemption in the do not call list for Chimney Sweeps? I seem to get marketing calls from a lot of them.

no messages was left.

This is a Masonary Company looking to sell "specials" on Chimney Cleaning.
I asked why he was calling me? I am on the Mass & Nat'l do no call registries.
He could not answer why, and did apologize.
Before I hung up, I stated clearly, "do no call".
What good it the registry, if these companies seem to think they are exempt?

Received this call at 10:35 a.m. on 07/31/2010, no message.  Caller unknown.
