Airtel — deducting money unknown

Address:

E-205, Vasavi Dreams, Czech Colony, Sanath Nagar, Hyderabad, Hyderabad, Andhra Pradesh, 500018

My airtel number is [protected] i did two top ups with 10 rs each i didnt even call single number and airtel deducted all my recharge amount. This is strange to me i need to call two important calls so i did 10 rs each. When i tried to call that no it says balance zero. I never used thosed 14 rs after tax cuts still i was not able use those topups because airtel deducted. Well this condition i will switch to other network.
