[Resolved]  Idea Cellular — billing charges

Hello,
Idea customer since last 5 years.
I want to register a complaint about my last billing charges which is 592 in total.
There was a data pack of 250rs activated on this no ([protected]) and has not been activated by me. Because at the same time my phone was in service centre for repair and the sim card was with me without inserted in any other phone.
I had registered a complain about this and customer care representative said that problem will be resolved in 1 hr but it has not been resolved yet and the data charges are added in my bill.
My total bill for the month july (I. E 24/6/2017 to 23/7/2017) should be 251 excluding gst and including gst it comes 296.18.
I had sent an email few days before, called om customer care no and filed a complaint and also visited idea customer care service centre but got no response from any of them.
I want someone to looks into this otherwise i won't pay the bill and if you are going to disconnect my sim card then i will have to file a complaint in consumer court because i have all the required proofs.
The time when the data pack got activated was 6.14 pm on 14july 2017. And i got my headset back at around 6.45..
