Vodafone — Vodafone auto deduct from account balance in the name of "VIDEO", which is totally something not requested

On November 24th 2020, i received an sms saying,

"Hello!
Thank you for downloading VIDEO from PlutoMobile.
You have been charged Rs. 15
Your balance is Rs. 27.26"

It was said third party download happened. I am 100% sure that i didn't download anything related to such. How come this has happened without my knowledge?

This is not the first time that vodafone has deducted money from my account balance for unsolicited services.

I see its happening as common problem for many people, eating away ones account balance and then customer care just saying "third party content download, cannot do refund". Please have at-least the process to do the refund in these cases, when a person gives all the proof for not downloading such content and please please be customer friendly.

Other suggestion - please work to improve your service and stop/block these third party download by default itself.

Thanks
