Amazon India — power acoustik car equalizer by amazon export sales llc

Order #[protected]. I booked it on 11/09/2018 paid win advance. Recieved it on 20/09/2018. Got it installed on first week of oct 2018. One channel is not working from the begining. Contacted amazon on 27/10/2018 thinking the product has some warranty but got a reply return window closed!! I paid rs 3739/- if i have to return now they will pay back 1614/- balance is shipping and import duty deposit. They are not ready to repair and return the product!! This is absolute cheating. Some chinese crap they sell online saying its imported from usa!! And the buyer is cheated and no where to go. Product is faulty since day one. Whattype of business is this??!! Govt should look into this seriously. This is "amazon chor bazar" sell and shut the door. God knows how many millions are effected and cheated by this company.
