I have HTC 3400i handset which is still in warranty. Within span of a month earphones began to malfunction. So I visited its service center at Vikroli. They promised to return me new earphones within 15 days. But I had to visit the service center for 5 times as they failed to return earphones even in 2 months. Lastly after some arguments ( they even dont respect or care for customer ) they handed me earphones that were repaired not even the new ones. Within a day or two it started to malfunctioning again. I dont know how to deal with them as even thought of visiting customer care ( which is 45 min away from my home) reminds me of their previous service.
