ICICI Bank — One Assist Wallet Assist

Recently I was contacted from ICICI Bank regarding the one assist plan. Without asking if I was interested in this, they started describing about the process, benefits etc., of this one assist plan. And without asking if I was interested in applying for it, they just said you have been enrolled into this plan and every month Rs. 1899 will be deducted. I never gave my consent and yet now I have been enrolled into this program and today at around 2:47 p.m., I received a mail saying Rs. 1899 is debited from your account. I would like to withdraw from this and i would also like a refund of the same.
