Whirlpool India — Improper installation of AC

I have purchased whirlpool AC in Jan 2022 and the installation was not done correctly by the whirlpool technician, i have raised the complaint for the same to the whirlpool

During May 2022, i faced issues with AC cooling and again i raised complaint for the same

Now again i faced the same issue and raised the complaint for the same IND[protected], the technician found that the AC gas has been leaked from the coupling due to incorrect installation
and now i have to pay charges to get gas refilled

Due to improper installation i am facing multiple issues with the AC right from the start which is such a bad and hectic experience with whirlpool

I want to escalate this issue to whirlpool and want my AC to be fixed ASAP by the whirlpool
