[Resolved]  Idea Cellular — charged 15 rs fakely

I got a call from +[protected]. It was a recording so i cancelled the call.
I immediately got an sms saying "thanks for downloading sports from one97, your account has been charged rs 15"
I have never downloaded anything on my number [protected] or signed up for any value added services (Vas).

Horrible customer care from idea:
When i called idea customer service, they tried to divert me from the topic by saying that i must have signed up for vas so i got charged.
They are lying. One of their supervisors admitted that they are aware of this issue and have reported it but cannot refund.
