We have been using Airtel broadband since 2008. This year on 21st Oct'11 we decided to go for wifi ( i know it is late but we were lazy). Their guys came and installed a new router and it was good. But, the router suddenly stopped working on 31st Oct'11. After repeated complaints they said the router is bad, so we asked them replace it. However they told us that because it is more than 7 days we cannot replace it. We were surprised as the bill says warranty for 1 yr.
Any ideas as to how to go about this?
