Vodafone India — unfair deduction

Address:

Jodhpur, Rajasthan

Everytime whenever my balance is more than 50, they deduct it and even they don't inform us
There is no msg no, no notification of deduction. When i call them they said it will not gonna happen again and refund my amount
But this time they deducted my 100rs and saying it won't be refunded. How am i gonna know that my balance got deducted, if they will not inform me. They don't send a msg or not even any notification.
I am a student how can i afford this again and again. I know which service is chargeable or which not. This deduction is just to rob people's and don't even inform them.

I am tired of complaining them again and again
I made 10 calls withim 2 months
I am # disturbed by this thing and gonna take a legal action against them.

First of all refund my all deducted amount and then if this happen again. I will change my sim and goint to complaint in a legal way. I am going to complaint in consumer court against it
