Pure IT — Improper response & service

I have purchased pureit water filter on 10.12.2009 d same day water was leaking which was complained to Mr.Jegan, Adambakkam, BrindavanNagar branch.No action was taken on their side, but d pblm continues.Oly handwritten bill was given.On 9th, Mar, 09 again d complaint was made but no response.Then oly v came to know that they hav wrongly delivered d product(blue instead of red as per invoice)which v hav ordered and after fighting oly v got the invoice after 3 months.But still d pblm continues as far bcoz d device no in invoice and device no in our product doesnt match...
V hav informed d pblm to d branch manager to but they are making us to bare the battery cost even before it comes to red tat in warranty period(bcoz there was a crack near battery which was a fault during delivery)...V havnt expected a very poor response, service and negligence from a reputed public limited company like hll!!!
V wanted d company to take action reg replacement of product...
