Tata Docomo — unwarranted deduction

Address:

Ranchi, Jharkhand

My no is [protected], and my complaint is that a amount of Rs 30 is deducted on 3-12-12 from my balance for a value added service which I never activated. And when I tried to reach customer care executive on 121, 198, and [protected], there was only computer operated voice and there was no way to reach customer care executive and register a complaint. Can you please help me in this. Because this is now become general thing . every time now and then they siphon off my balance. is there any provision in law for action against company?
