I have taken post-paid connection (Rs.999 for 1 years) plan from Airtel Delhi in May'06. At that time I have asked Airtel executive about the international calls. He had told me the call rates of the international calls. When I called up on Airtel customer care, they said I need to pay 1500/- IRS or it will be activated after six month. Now six month have passed when I called up on Airtel customer care again they said I need to pay 1500/- other wise you can't get this facility.
