Lloyd — Worst after sales service and service engineer attitude

Its really the worst experience ever with any service engineer I faced today.
I raised complaint for the ac repair but the mechanic came only to switch on the ac, checked some voltage for a second and spoke just some rubbish unrelated issues which he didn't want to do right there. Immediately demanding service charges without solving the issue. As I forbid to pay the any charge he left the place by saying find yourself another engineer.
What kind of service are you providing??
We don't take service from company to listen rubbish from your engineers. We need real service.

Attached #retail invoice, #warranty card(showing complete coverage including gas leakage repair) but your service engineer is saying leakage repair won't cover in warranty.
