AO Smith — no after sales support

Lodged a service request #10742094 on 28/11/2018 but the complaint has not been attended even after 72 hours. Have sent numerous emails to customer support and even made calls but every time i was provided assurance that i'd be receiving a call within the next hour. 72 hours have passed and counting and still no call whatsoever.

Terribly disappointed with the after sales support of ao smith india. They make tall claims of 1 hour callback guarantee on their badge but in reality they don't care about their customers.

Never should have gone with ao smith. My trust on ao smith has been completely ruined.
