This is a game plan people use to fool all of indians residing in rural areas. This Airtel makes so many adv. about its bill payment status but foe example I, using Airtel -Tamilnadu mobile with a/c no starting 114-********* unable to pay bill via any of internet / bill gateways because they want only city related bills only. If you go thro the AIRTEL WORLD payment gateway our city bank when it says it accepts any other VISA credit cards it spits wrong reports as " date of expiry not correctly entered " or " you don't have sufficent funds " etc. so can't use the system. If you prefer to make complaints to CITI bank or AIRTEL, simply no answer and your complaint automatically closed after a while.
