Airtel — rs.75 deducted automatically with multiple times

Hi
I am using airtel prepaid number [protected]. Since last 1 week, airtel deducting rs.75 for smartskids package, again rs75 for schoolzone... For somany other packages... Which i was not activated.
Airtel activating automatically and deducting rs75 multiple times. Whenever my balance is over rs75.. They are deducting. Contacting customer care now a days very difficult.. They have some many options so that you cannot reach them to talk. Since last 1 week i have lost more than rs.400 rupees with this automatic activation. Even after deactiving any service, they are again deducting rs.75 with some other name.

Kindly help to revert the amount.
