Vodafone India — Content download charges

Hi,

My phone number is [protected].

In my Vodafone bill dated 05.05.17, I have been charged Rs. 50 as content download charges. I do not have internet active on my number. I do not know how can I download something.

When I checked with the vodafone customer care, they say this is been charged by a third party! If it is a third party, why would it come in Vodafone bill.

As far as I know I have not donwloaded anything, and I want a refund of Rs.50 + whatever tax applicable for the amount.
