Tephie's Personal Bombshelter MarkII

For "Financial Solutions". Why? The motherfuckers keep calling me. The first time or two I just hung up, my only phone is a cell and I don't like paying for junk calls. The next time I listened to the message and pressed 2 to get off their list. I did the same the time after that. Today however I pressed 1 to get a person:

Fucktard: Financial Solutions, how are you today?

Me: Fine, but you've called me four times and I pre-

Fucktard: *hangs up*

Me: ...ssed the do not call... twice. *instant hate on*

So, the next time, shall I just hang up and live with the fuckers calling me? Press 2 again and hope the third time is the charm on getting OFF their fucking list? Press 1 and immediately say "Give me your supervisor"? Or maybe "DO. NOT. Hang up on me." and then tell me to be sure my number is off their list?

Is there anywhere I can stab these assholes where it will hurt?
