[Resolved]  Whirlpool India — defective windows ac delivered to me

I purchased a brand new whirlpool window ac on 4th may 2019 from amazon. It wasn't cooling so i logged a complain so far there is no response from amazon or whirlpool. They just said a technician will come but whenever i try to reach any technician from their provided number of local service center and also on their global email id of cs team [protected]@whirlpool.com and [protected]@amazon.in. They just say someone wil come but technician says on call they dont handle complaints or installation for ac. Someone else will come.

Please help me as i paid full to amazon and purchased a new ac and nobody helping me
