I am glad someone has written so clearly on lack of customer service at this telecom giant. I am a NRI and visited India during summer months and mistook Bharti as the best company and got their lifetime mobile number. Forget lifetime, number was discontinued for vague reasons just after a week. I re-submitted all the forms again but my number is still disconnected even as I have returned back. I could not use the LIFETIME mobile for all practical purpose beyond first week. God help them.
