Vodafone Idea Ltd. — Without consent Rs. 49 charged from my Vodafone prepaid sim.

On 13th December 2020, Rs. 49 was deducted from my prepaid Vodafone sim without my consent. Suddenly the message popped up and later I found that Rs. 49 was charged. I am completely unaware about what action of mine made them deduct this amount. I want my money back into my vodafone number. A completely unauthorized and illegal way to steal people's hard earned money. Shame on mydala and vodafone idea.
