Adding one more complaint. I did face similar issues like the rest. Support number always busy, initial attempts to make calls didn't succeed, not able to login to website, etc. As someone pointed out, big infrastructure issue: launching a service that's not ready for the call volume. However, after couple of unsuccessful attempts, I was able to make calls and I did indeed get the double the money offer they promised. The Call quality to the cities seem to be okay but to the rural areas, there is quite a bit of echo. I am trying to use up my money and go back to Reliance (although, those guys seem that they cannot make up their promotional offer - one day it is double the offer up to $50, next day it is up to $10, next day it is some arbitrary minutes based on the what the prepaid amount is). The Call quality of Reliance is definitely superior to Airtel and I never had any problems connecting. With Airtel, did anyone figure out how to update the registration numbers without getting any error. It looks like the stupid system asks for PIN even if you are calling from a registered number.
