Bonanza Portfolio — Unwanted telemarketing calls

I have registered mysel[censored]nder DND. I have never heard or interacted with this company. In spite of this I got a call today from this company for investment. May I know how my details were procured? Looks like my details and other customers are been peddled and sold to companies like yours.This is a recurring menace and is offensive. Please think for once from our side. I have been getting calls from every Tom, Dick and Harry, from different cities. I am fed up of intimating every every other day that I am not interested in taking a personal loan, credit card, donation, etc. STOP this dirty practice of telemarketing once and for all. If someone is interested they would approach you. Don't pester the rest for your cheap financial gains!
