Airtel — superstore service

My name is k. S. Chidambaranathan and i am an old man of 77 years. Suddenly airtel deducted rs. 99/- from my account saying that it is for superstore service. On enquiry with them they have told me that i have activated it through net. I am not using smartphone with net connection and i wonder how could i activate it through my mobile net. I also don't understand what nonsense the airtel's superstore service. It is only a airtel's superfraud service. They refuse to refund the amount to me which was taken from me by some tricky and fraudulent way. They are stealing their customers. I am going to change from airtel to some other genuine providers.
