My service agreement is not to "allow" anyone to call me.

Can you show me that in your service contract?

You are forgetting that, service agreement or no service agreement, there are laws against "harassing calls" from individuals. Telemarketers should be no different. If we ask them not to call, they should immediately cease and desist. If they continue to call, it's no better than the phone pranker.

(And worse, it won't get them any sales. Unfortunately, they're not smart enough to think of this.)
