Reliance Gsm Service — imposed unused charges

Sir,
This is Pradip Saha. I use reliance gsm from 8 months. My mobile no [protected]. From few months I saw that they deduct excess of call charges which I am not used. But it is Rs. 2 /- or Rs. 5/- . But 25th October I saw suddenly they deduct Rs. 30/- . I contact customer care. They everytime said that our system slow or system is now going upgradation please call after 2hrs. From 25th oct to 29th october I call more than 15 times. my last I call was 29th october at 12 noon. The day the customer care representative also call same that system is now going to upgrade plz call after 2hrs. I say plz give the call to ur senior. After hoding 3 min. their senior attend call and said u use mera gana services. I denied because I dont know what is mera gana and also I am not interested also hallo tune. I never use this service. He angrily told me that u use this service and we do not refund any money understand next he cut the line. I have also voice recording data of the caller. Plz do something If possible.
