Idea Cellular — Idea deducted money from my balance

I live in an area where I don't even get an idea network. Airtel is my new sim here and my idea number is mapped with the account, I am keeping it activated. But as there is no range, then no incoming, no outgoing, no SMS still Idea activated VAS services, hello tunes from March 2020, and deducted around 150 rs without even informing me. One day I was expecting a call from my bank thus I kept my mobile in window area where I can get some range [it's mobile but I have to keep it at one place like landline] and I got an incoming IVR call which I disconnected exactly at 10 secs and money got deducted. then I came to know that in past as well, they kept deducting all my balance - I made just 1 or 2 outgoing calls in the last 9 months and this fraud company kept deducting money by activating services. This is cheating and I need my money back.
