1)Every month they used to deduct roaming charges 49 Rs/-, the reason they said it was used in roaming when I went Gujrat, As a matter of fact I never went to Gujrat Infact I never left Bombay.
For 6 months it continued the same thing. I have no idea how did it showed Gujrat on there Records when I never left Bombay.
2)One morning I got up and saw my balance -164 RS/- (a negative amount of 164). When called they said I downloaded some services. In fact my mobile was the most simplest of all phones with no downloading feature on it. I had to fight to get all money back of Rs 260/- in positive.
3)When I went to pune I could not recharge my phone through roaming. When asked they were helpess they could get my phone started.
I faced innumerous problem with Airtel... It was like a never ending story of torture for me.
