Replying to What is the best way to annoy telemarketers?

So I keep on getting a call from telemarketers asking for a deborah. Well my name isn't deborah and I keep on asking to be put on their do not call list. Anyways I always get called from a different strange number always asking for a deborah. Last time I asked to be put on a do not call list, the telemarketer said I will call you every fifteen minutes until Jesus comes. So anyways how can I annoy the shit out of a telemarketer. I need good Idea.
