[Resolved]  Vodafone — Bill amount charge

I have taken a free amazon subscription from the idea (now Vodafone) on 21.08.2019 that goes till one year i.e. 21.08.2020, I have canceled the services on the same day of expiry, and the amazon prime subscription is also stopped on the same day. But the company says I have not informed them and they charge me 1000 rs/- this is a scam to general people like me.

If I didn't inform them about the subscription they why did it end in the first place..pls do some Justice all those people call me back from the idea speak Hindi and I speak Telugu they didn't understand me at all.

My parents will kill me if they found out about this, pls help
