Kaun Banega Crorepati — fake mail

I have received mail in my wattshop as well as call from kbc logo no [protected] on 04th sep 2019 that my lottery no 83315 got rs. 25 lakes and given kbc side to confirm my winning. I have seen the side put my mobile no and lottery no. That shows congratulations you win rs. 25 lekhs. Then i have informed them, that gentleman told me that i have to deposit rs. 15, 000 in this a/c no - akash mandal account no : [protected] sbi then i will get the winning money, if i am not sending then my file will be closed. But i didn't send. Like this so many mail coming to my wattshop. Kbc side has given this no [protected], i have tried so many times but they are telling it is invalid. I am asking from kbc authority that whom i will contact for registration in kbc on line lottery? [protected] dr. Benoy kumar chattapadhyaya pune maharashtra.
