The problem with Airtel is that the voice quality is pathetic, network is always clogged, there is huge amount of call drops, so i really wonder what they keep advertising about ? You write hundreds of mails to them, visit their customer care center, but it does not make any difference to them, they are just so ignorant !! Worse then Airtel is Reliance, you take up a connection, use it, dont find it satisfactory and want to surrender it ?? that where the trouble starts. First, they will never process your request, second if you ask them to give a clearance letter while making the final payment they will never give you one. After all the follow up you have to do with them for the dis connection they will finally send you a legal notice for the amount payable till date. The govn is not bothered and neither is TRAI which is the governing body as they get their fat packets on a monthly basis from these big business houses. Fact of the matter remains that consumers ie we are the biggest fools who try to find a good service provider in one of them. How's Vodaphone doing though, they say they are 'happy to help'
