Mydala — Access charges

I have been charged Rs.49/- on my phone bill stating that the charge for choosing to access mydala powered deal on 23rd March 2021. I checked with Vodafone, they are also not aware of any VAS provided for this facility and neither authorised any vendor nor set my Vodafone postpaid phone as a payment option to charge me. So it's a fraudulent activity taking place to charge someone without their consent / knowledge!
