Worst customer support. I could not use account in last few months my account becomes dormatt. I try to unlock my account no response your calling time billed and wasted. Afterlong call it says system problem ended call. I tried few times it went to same wine. Even I do visited customer care airtel centers in Hyd both says call 400 end of the call says system problem try after some. SO BEAWARE this they says they answer 100% calls its not sure please keep do a review and do write your own ratings
