The way I handle spam/scam calls.

Usually I get 3 types of calls. Credit Card, Stock Market and Loan related. Things I do and have worked to stop those calls. Credit Card: I tell them to send 10 credit cards in a sarcastic way mentioning I want to sell plastic to Kabadi wala. Usually the call ends in 10-15 seconds. After getting that kind of reply 2-3 times they will stop calling you. Stock Market: Most of the time their opening statement is "Hello Sir, Apka trading ka kaam kaise chal raha" followed by hamare company ke saath join ki jiye daily kar z-y-z % profit dilwa denge. I reply as if I don't know what trading is?, what stock market is?, what they do in stock etc.. and start asking them questions like where did they get my number. They try to convince me that my number is registered with a stock broker, I start asking what is stock broker, what is the name of stock broker, what they do in stock market mentioning that I know only SAABZI Market. They also stop calling me after 2-3 calls. Loan Related: When they call, I first listen to them, then I deny the loan offer and start asking for JOB to them as I do not have any. Or Ask them absurd amount of money 50lakh - 1Cr - 5Cr. When they ask for income proof tell them you don't have job. I have tried and tested all of the above options. It worked for me.
