[Resolved]  Vodafone India — improper billing of rs 560

Address:

B 82 Century Tower , Bh Hotel Grand Bhagwati, Ahmedabad, Gujarat, 380054

I have been charged 560 saying that i have dialled the number 51717, wherein i had never made this call. Also the information reveal that the call lasted for more than 30 minutes. When i called the vodafone care they refused to delete such faulty billing. I don't understand why these companies making a fool of the users.
Im holding this number from more than 10 years.
