I had bought airtel prepaid connection from TIMES UTSAV exibition Airtel stall . unfortunetly I was not carrying my GSM phone so I done all formalities & took the card when I put the card in my phone it was not activated so I called up aitrel customer care who told me that they have not recieved confirmation SMS from dealer hence it will not be activated I waited for 5 days and finally submitted documenta again at airtel galary and then the card was active which was showing the validity of only 15 days hwen complained they told me that the card is activated 15 days back by the dealer & they can not do anything. This is not the end as they had mentioned 330 rs talktime but actualy it was 200 & 130 airtel to airtel which is useless and if u call customer service u get arrogant & childish answers so pls pls pls avoid AIRTEL if do not wish to pull ur hairs in agony
