Idea cutting money for the service of sms yoga pack which I never opted for

Hello team I never opted for a yoga sms service and without my knowledge idea company deducted my the amount, when I called to customer care they were not bother to reply why the amount deducted dey just told me to call after 4 days the system is not updated. And when we call after 4 days they tell there no news in the system about that transaction and they message that full talk time for 55 ruoees and 65 rupees and when we go and charge we get for rs 49 for 55 and 59 for 65 when we ask the shopkeepers dey tell dat would be credited later dat never ever happens. Idea people are bluffing and earning money from customers very bad service. I need my money why I need to spend my money for them. Hence I need to place a complaint with appropriate department and sue for the damages. Kindly help me in this regard
