Amaron — battery not running

Address:

West Delhi, Delhi

i have purchased an amaron shield invertor battery on 12/04/2009 and just after 2 years it has stopped working and there is not even a single minute back up and the phone numbers given on the amaron warranty card are not working and i want to know that it is the only life of a battery i.e 2 years and if this is the case amaron company is making fool of all the consumers and for this i want my battery to get replaced........
