Videocon Mobile Service — wrongly caller tune charges debited to my account

Address:

Gujarat

I am holding mobile connection [protected] and I have made first recharge of Rs.62/- , when I had checked today I got information that the balance is Rs.16/- , On enquiry I was able to findout that the on 15th, Videocon gave call and debited Rs.45/- towards caller tune. I have not used this phone since I have four more mobile in the house.In fact there is no need to activate coller tune. I understand that this is the way Videocon is generating money from customer.
I have requested to discountinue this service and credit the amount of coller tune in my account. provider customer care has refused the same though there was none of my fault.
