India bulls dhani One freedom credit card - Daily calls forcing me to invest in the Freedom card

I installed the app and uninstalled it. From that day on they have made my life hell. Every morning they call me up although I said I'm not interested, & disturb my sleep. I work UK timings and i end up getting disturbed and unable able to sleep. Specially getting up on that note spoils my sleep and my day. Unable to sleep after that. I need to complain about them so action can be taken to regards to harassment. This is total harassment. Everyday i tell them I have no interest and yet they call. It needs to be reported. This is just not right. They know I am not interested and still harassing me to invest in something that i don't want? There is no question of second thought also. When i hear the word dhani now or see it, my blood boils. I need to report about these guys about harassing people into buying. If you don't buy they end up making your life hell. This needs to stop!
