Voltas — Voltas AC Issue

Dear Voltas team,

We purchased the AC but within 2 years the gas leaked and the way the technician refills the cooling gas, At a 16-degree temperature it is like a 30-degree temperature.
Feels like the service is very cheap.
I never saw the cooling gas in Voltas cylinder it appears to be an unbranded cylinder and we do not know whether they are putting appropriate amount

I would recommend consumer to buy other brand's A.C, you will definitely get offers on Voltas AC, to will looks appealing, but what about after sales service, the moment your AC gas is leaked for the first time then the AC is not worth keeping since the 3rd party service centre will not provide you the same service which a branded company directly can provide.
Please don't buy this ac.
