Quite rude. They always hang up abruptly once they realize I’m a big nose. I guess their company does not teach them how to politely end a call.
Now when they call I just start off in English so they bugger off faster.
Could that possibly backfire on you? Say for example, you damage someone’s hearing that way. They have your phone number, could they sue you for personal injury?
It’s better just to hang up on them while they are launching their spiel about whatever they are selling.
While they’re doing something illegal?
Go ahead, cut off the nose to spite the face.
Just saying, maybe screaming into the phone isn’t the best strategy.
If this question is serious, there’s either a problem with a society or with the person asking.
It’s a poor slob in a boiler room trying to earn a living.
Usually just speaking English is enough to scare them away. However, I give props to those who try to work within my Chinese knowledge or attempt to speak English.
I think I taught a loan shark a new vocabulary word or two but most sales calls I just say no thank you
I think once got enough information to get a free subscription to mod one time.
I passed the information on to my wife…
I also got a free 3-month loan of a wireless iPad from the immigration customer service department.
I really did think it was a scam and they had to convince me otherwise.
Anyway unlike it used to be in the United States where the cell phone owner had to pay for airtime regardless of whether it was an incoming or outgoing call, the caller pays everything here and that’s why the cell phone companies like these callers
That’s something from last century in Europe.
Yea which is why most people got unlimited plans, because you paid to receive or send calls/texts.
So when people complain about getting sales calls on their cell phones, it means absolutely nothing.
Back then it cost money. Now, you just hangup. My sympathies lie with the poor slob in the broiler room trying to earn a living…
As for relying on caller ID. I have friends who know in the states that I have to hitch rides on free services that don’t provide caller id. They just won’t pick up the phone. They’re afraid of possibly talking to strangers.
I didn just fine before those services were invented. My daddy told me how to handle strangers on the phone. What to say and not to say. Stupid wimps.
I have a new approach to answering these calls, feel free to join me. When the sales spiel starts, I put on my best John Cena voice, and say the following, with volume:
"Woyao jinyaodai.
Wo yongyuan buyao fangqi
Wo shi guanjun."
Did the trick tonight.
Good idea! Are you still just leave the phone on without saying anything, and let them blabber on until they hung up. However, I realized that that really didn’t do anything since they weren’t paying much for the call if anything. Now I just let them carry on and answer them in English. After one or two sentences of English they hang up immediately. Pretty much scumbags.
I’ve been getting a lot of them recently for some reason. The odd thing is that immediately saying “Sorry, I don’t speak Chinese” (in English) does absolutely nothing - they just keep blabbering on until the end of their script, no matter how many times I say that.
You’d think they’d want to save some time and hang up immediately, but they just keep going. Now I just say that then put my phone down somewhere and don’t respond further, while they continue to the end of the script, ask me whatever question it is they’re supposed to ask, then eventually hang up when my end is silent.
I have the Whoscall app on my iPhone - if it shows a call from a known SPAM number, I decline directly.
I just ignore >95% of phone calls anyway. It’s 2021 - people can send a message or e-mail if it’s anything important! 
You have to be as persistent in talking over them as they are. High level English too, such as “Your proposal is of great interest to me; however, due to mitigating circumstances, I may be unable to fulfill the requirements of this suggested contractual obligation and, as such, would prefer to postpone further discussion of such arrangements at a mutually appropriate time.”
Or random bs. Both work in my experience.
Haha. But I don’t really see the point of insisting…if they just want to waste their time keeping talking over me with some spiel I can’t understand and I’m not listening to, who am I to stop them? 
My hope is I’ll make it onto a “do not call” list of some kind. Haha, not realistic but I still hope.
Many are recorded messages, at least the beginning part so it will just keep playing. I use Google Phone on Android, it’s extremely effective at identifying spam calls, only 1 let through in the last few months.
Which one do you use?
They probably get paid per complete phone call time.
And Android weeds out many SPAM texts and phone calls.
