Why is ZERODHA giving client mobile number to spammers

recently , not even a month , i got a new mobile number, which i have updated to 1 bank and zerodha.
i have not given number to any site or anywhere else, yet i have started to get spam stock recommendation (same message) on both the numbers,
i have seen some topics about this issue here before, and zerodha guys said, we dont follow those kind of practice.
i am at loss of words, dont know what is goin on at zerodha,

anyway how to raise compains regarding those tips, does nse or bse have site where i can register complain about those bogus stock tips,

A post was merged into an existing topic: I am getting a lot of unsolicited stocks tips SMS messages ever since I opened a trading account, how do I stop these?
