Sony India — home therapy system

Purchased sony home theatre system 3 days back at durga electronics, raichur city, karnataka. They have not yet responded for installation... They had promised for installation within 1day... Even though we have contacted sony service centre raichur many times they have not given satisfactory consumer response... Hereby i complaint against their services as a unsatisfactory one... Kindly take action against them.. Or else i'll return the product back... Thank you.
