Axis Bank — One Assist

I have never agreed for membership in one assist. They registered on their own. When first time my money was deducted i ignored it by thinking it’s a one time thing. But now again my money is deducted. I don’t want their services and how can you just agree to membership without my consent. I want my refund back asap. Previous one too as i never agreed for it. Very unsatisfying services from axis bank. I would like to delink my account from axis bank if such problem persists.
