Vodafone Idea — Charging Rs. 25 unauthorized

I am having Vodafone mobile telephone connection.
I received a message from VZ-ViCMS on 27 April 2022 at 3:16 PM stating that
"HeIIo! Thank you for choosing to access Contakt Gaming Service, You have been charged Rs. 25."
I have not chosen anything as stated above. I have not authorised Vodafone Vi to charge this amount through post-paid bill.
I request for the refund of Rs. 25 so charged.
