Whirlpool India — whirlpool inverter ac

I. D. K. Sharma bought 3 nos whirlppol ac 7 months back, one of the ac was having compressor problem from installation, earlier their service provider denied accepting the same, after confrontation, he agreed to report compressor problem and get it replaced, for over 3months i am waiting for the same to be replaced, there has been absolutely no communication from them against various mails & telephonic calls logged by me, totally disappointed service support, never experienced from mnc company till now. May be in life i will never buy whirlpool products again
