Su-kam Inverter — non-performence and non-fullfilment of warranty clause by the company besides most unsatisfactory service

dear sir/ madam,
for long time since this January I have been getting problems of very low time backup by the Su-kam inverter. the customer service back up at dehradun was changed location and personnel and is maintained at very low scale. company, s engineer visited on 12/02/08 and made a field service report no 62048 which states that set is ok but battery is weak and he informed us that battery needs replacement. as battery is under warranty for two years and warranty is still on, he informed that he will take up the matter with company. i also lodged a comlaint wth national cutomer care executive vide no.[protected]. the sl no of battery is SMF - X6 E 05342 and date of purchase and ensuing two yarwarrenty is 08/04/2007.
but even afer several calls and reminders over phone and 3 emails there is no remedial action as due from Su-Kam.

with regards,

anil kumar
