Luminuos Invertor Complaints & Reviews - False Commitment

I purchased one Luminuos battery in the month of Aug' 2010 thru their Dealer Grewal Electronic Point with the warrantee of 24 months ( model LET -180)
FALSE COMMITMENT;.Now after 22 months they are refusing to entartain as the warrantee is 18months .
POOR RECORD MAINTAINENCE : Though their product bear the serial no and barcoding stil they cannot track the small but important first level information like which product or serial no from their warehouse has been sold to which dealer , clearly indicate their stock maitainence and movement.
Without customer purchase bill they will not entertain the complaint clearly reflects the customer support.
WORST CUSTOMER SERVICE: do not have any escalation process if the complaint is not addressed properly. Their personnel refrain attending the calls and if luckily attended their reply is we have other jobs also, cudnot understand what is more important than addressing a client who is following for 5 days.
HIDING FACTS; The product or system knowledge their engineers is below standards .They do not even give the customer copy of their visit report thru which they register the complaint and their findings which a customer signs.

Feedback: Thru this i would suggest ,PLZ DO NOT TRUST LUMINOUS PRODUCTS BETTER PREFFER LOCAL MADE OR OTHER BRANDS AVAILABLE. i WUD GIVE 2 OUT OF 10 TO THEIR AFTER SALES SUPPORT.
