You're missing out on fun. My favorite games I play with surveyors and telemarketers:
press a button whenever they talk, act like you dont hear the noise be VERY polite and apologetic, If they get angry ask to speak with their manager. ( this one REALLY pisses them off, has ended with them calling me back to cuss me out, which of course just leads to more button pressing)
lead them on with fake answers, really drag out the call pretending not to understand the questions.
learn how to say "I dont speak english, do you have a _______ translator in 4 or 5 foreign accents. Keep telling each translator this in a different accent.
just be abnoxiously condescending the whole time.
keep putting them on hold. Use a believable excuse then escalate to longer and longer excuses that are still believable. Try to get to 2m long excuse.
complain that you cant hear them they are too quiet, try to get them nearly yelling then ask to speak with their manager.
