Consumer Redressal

Good evening Sir/ Ma\'am, I am having a airtel broadband connection at my home & wanted to install a new Airtel broadband connection in my office. So, I had purchased a new D-link modem for my home & shifted my original modem of BEETAL 450TC1 ADSL2 + Router to my office. But the Airtel executive told me that the old modem is not working properly & since it\'s under warranty you can get it replaced by Airtel by making complaint of the same . So, I made complaint of the same on 4th july via reference no. 35136436 at approx 9.58 pm (since, my modem\'s warranty is till 9th July 2013) then I agian called you in the morning and your executive from Airtel told me that modem will be replaced by evening but to my shock, my complaint had been closed with no reason then I again made a complaint no. via ref no.:- 35194076 but they had closed this one also. I had contacted their Customer Care, Nodal Officer, Appeallate Authority, & to their corporate head via mail but no response yet.
