Vodafone India — Deduction of balance and getting bad response from customer care

Address:

110096

As from 4th january there is a deduction of 20 rs.
but as i did not download any chargable content from play store.
but there is redution without my permission.
when i called customer care.
i talked with Miss Suresh Rani..she just told we cant refund that amount as we are saying you download that than thats it.
when i asked her to transfer my call to any senior person, after a long wait she said our all senior executives are busy so you can mail us at our mail id etc..

so i just want my money back, as its not about just 20 rs, its about,
if i am not wrong then why should i pay..
