GoAir — received damaged luggage

I travelled from go-air from pune to delhi. My suitcase which i received at delhi airport was damaged with handle broken. I looked for go-air help desk for help, however just saw one single person who was almost asleep. I showed him the luggage and he casually replied, we do not address these issue. He asked me to email at [protected]@goair.com. I emailed at that moment itself and also tweeted. I kept on following up for more than 10days (See my twitter). Every time i would get response saying the team is looking after this and would get back to me. After 12days, they replied to my email saying it's not airline fault and this should have addressed at the ground staff itself. But the question is where was the groud staff available in to address the issue. The suitcase is now of no use and it's so irresponsible reply from goair. While there are rules in place for unruly passengers, but who is going to take care of such unruly and irresponsible service provider.
