Koryo Window Ac — never buy a koryo product

I purchased as 1.5 ton koryo window ac from ezone, saligrammam branch, chennai. Hardly 5 months and 7 complaints registered with no service back up. I was cheated on the product. The ac is lying unused in my room, and refusal of service is stated for the reason that there is corrosion in my area, kotturpuram, which is the second poshest residential area of chennai. They have supplied me a 2015 outdated and unsold stock. Their senior pan india service head mr praveen kumar is a person with a bagful of lies and their store manager mr balachandran is very discourteous and unsuitable for that post. Beware of the staff of koryo and and ezone.. I am looking to taking legal and criminal action on the company for cheatint a customer. My advice. Do not take home any koryo product even if offered free.
