I've been getting so many calls lately, I've been playing music for them lately, trying to waste their time, hoping that they will take my number off whatever list it's on... I really wish there was a way to waste more of their time. Thus far, all I've determined is that they don't like Ace of Base.
They might actually start calling you more because the reps get incentivized by talk time, so getting a chance to chill and listen to music instead of actually having to talk to people and try to sell scam things people don't want to buy is a refreshing change for them.
Realize those reps hate their lives, hate their jobs and are probably getting $11 an hour in some crappy hell hole trying to make $$ to feed their kids... it's not a job anyone WANTS to be doing and they really don't WANT to be bothering you, they are just forced to by their employers.
If you don't want the calls, just say, "Please put me on your do not call list, thank you and have a nice day" and then hang up. Asking for the DNC is crucial- the words "DO NOT CALL" is the magic phrase that will get them to put your # into the blocked list of the autodialer. Some scammier telefirms won't actually add you to their DNC list if you say "stop calling me" it has to be the phrase "add me to your do not call list."
Also if you just hang up on them without saying anything, the software will automatically add your number back into the queue to reattempt you again and again sometimes within days. Our outbound autodialer software used to recall people who didn't answer and also everyone who sent the reps straight to voicemail. The autodialer basically throws everyone back in to get endless calls in perpetuity until you pick up and the rep talks to you. And in a big shop where you've got 500 reps making 200-250 outbound calls per day, they can try you 1x a week forever.
So if you really don't want ANY more telemarketing calls ever, stay on the line until the rep comes on, then say "please add this number to your do not call list, thank you, goodbye."
People seem to have varying success, but I find that any even semi-legitimate companies will stop calling if you answer and ask to be put on their do not call list.
It can be necessary to talk over their opening spiel.
This is in the US for a number that is already on the national do not call list (which has lots of exceptions); I don't make threats or argue or anything sophisticated, just "Please put this number on your do not call list." Then hang up.
This never worked for me when I was receiving wrong-number collections calls, they would just hang up and call back the next day. What did work was hanging up, calling the number back, and asking to be added to their do not call list.
Debt collectors are actually more regulated than telemarketers, so once they are convinced you aren't the debtor, they will stop. I think the not wasting time on pointless calls is even more important to them than marketers. Even in the case that they are contacting the debtor, there are pretty strict rules they must follow.
Yeah, I did some research back then, and it didn't really seem to be by the books. Regardless, if they were the ones that initiated the call, they would all instantly hang up if I suggested they had the wrong number/person/etc and call again later.
