Airtel has started generating revenue from other way too. Please check your bill they start charging money which you never requested. This I am taking about my "REFERENCE NUMBER 38557248" i found they started charging money rs 75 per month extra without informing me and they say that this is for PC secure, which I never requested. This is the way Airtel is getting a big revenue and giving money to filmstar like Sarukh khan, bebo and all.
Please check your bill, I can say airtel is a cheater company not a CMM level company.
