Vodafone — Deductions on balance for 'my daily wallpaper'

Almost every month rs.19 to rs.49 is being deducted from my balance. When i checked with customer care they are saying it due to core balance dnld-wwap_dls0019_ppu_kin01467053 and ppd/ppu download dwap_gam0025_ppu_dat05002001 and it cannot be refunded.

First time i spoke to customer care in august 2020, they said its because i clicked on some ad's on mobile, and customer care assured me it won't happen again for the next 6 months. On sept 1st 2020 again rs.49 was deducted. When i checked, they're saying its due to cookies on my mobile.

Without any otp or confirmation or intimation from the customer, this amount is being deducted every month from my mobile balance.

1st september 2020 – my daily wallpaper - rs. 49
11th august 2020– my daily wallpaper – rs.49
6th june 2020 – my daily wallpaper - rs.19

I need a refund for this and previous amounts deducted
