@whirlpool_india Finally resolved 👍

[Dr Umesh @umesh_chemi]

Bought 2 ACs from @whirlpool_india via @amazonIN (Mar 3).
• 1 unit OK
• 1 defective from Day 1
• Temp fix failed in 2 weeks
• Replacement picked up → NO update
No response, false timelines, my number blocked.
Never faced this with my old @MyLloydIndia AC

@PMOIndia @UmangOfficial_ @jagograhakjago can you help in this @whirlpool_india is shameless I am out of option 2 months and no response from their coustomer serivice on mail, toll free, twitter DM

[Dr Umesh @umesh_chemi]

@whirlpool_india Still no resolution from your side. Please let me know it's summer at peak we need it urgently we don't have a year time to wait for your response. Please issue refund so I can get @LloydIndia product which never had problem I have been using it at different place for 10 years
