I called the District Consumer Forum this morning to enquire about the judgement I was told to expect in a week at my last hearing in October. I was told the judgement was ready, and that I should collect it. I did so forthwith.
Here's the interesting part (the last paragraph):
The complainant of this case has been subjected to harassment, he need[s] to be compensated. We allow this complaint and direct the OP to replace the battery in question within a period of 30 days with a fresh warranty of one year. We further award a compensation of Rs.6000/- to the complainant which will also include the cost of litigation.
The judgement was entered on 2012-11-05, and the office keeps one copy for each party to the case for a month; if it is not collected within that period, it is dispatched by registered post. I expect Exide will receive its copy in the second week of December.
The wheels of justice turn slowly, but they grind moderately fine.
