My Redemption Code is 90021485, As informed by HP, Airtel 3G/4G Dongle worth max Rs 1500 against the Airtel 16 digit code is RHW3IM6LQ53A0PB9, was sent at [protected]@yahoo.com on 21/07/2015 .I was advised to visit to the nearest Airtel store along with my papers for availing of this benefit. However the Airtel Office situated in Vasco-da-Gama, Goa refused to handover the dongle stating that since the 3G service is not available in Goa, they are not in a position to give me a dongle.Please advise what I should do to resolve this.I badly need a dongle.Urgent reply pl.
