Havells India — Ac not working for more than 15 days

Address:

133005

My Ac stopped working on 2nd of Aug. Engineer visited and order some parts,
it has been over 15 days no one visited after that, engineer do know anything, customer service keeps escalating the issue and repeating same sentences again and again, Like It will be fixed in 48 hrs and then nothing happens.
Change my Ac or atleast fix it.
Change your team that is at 133005 pin code first, they told me one part is not working and have ordered three as per customer care

I will never buy any havells product again
