Vodafone — Theft

Today on 02 Jan 23 @ 21:10 hrs Vodafone activated a pack called desitube on my no.[protected] and thefted Rs.21/- from my main balance and deducted my whole balance.
Dear Vodafone,
I don't know about of these plans then how could I activate them, who gave u the rights to deduct my main balance after thefting I don't have sufficient main balance now.
If I want any of your services i"ll go there & choose then pay for it and activate it. So, I want my balance back ASAP.
