Sony India — Without checking my product was returned to me

Address:

Paschim Medinipur, West Bengal, 721301

I am a permanent customer of Sony. I have 3 TVs, Sony Camera and a Home theater. I brought this home theater DAVTZ210 in the year 2011. My product stopped working after 5yrs. I live in Kharagpur. The service center is in Midnapore. When I went to Videoplaza Sony Authorized Service Center in Midnapore for service, they immediately returned my product without checking stating a reason of external part moisturized. My 1 day of work was cancelled due to journey from Kharagpur to Midnapore (14km). I just want to request you to take action against the service center as soon as possible for the inconvenience caused to me.
