Blue Star India — AC installed during warranty time, but not providing gas top up

Address:

Kottuckal, muvattupuzha

Hi, i purchased a 1 ton ac while i was in calicut in april 2023 and since i have to relocate to my town - ernakulam i uninstalled it through blue star team by august 23. But when i tried to reinstall it they charged me 1500 where as common charge in outside is rs 1000 only. They convinced me that gas warrenty will be available only if i do it through bluestar team. But now they arr not ready to provide gas top up. The manager says that it is the mistake of their staff, no such warrenty is available.
I used it for hardly 5 months and they are not providing gas warrenty and asks me to file a complaint to the top. Plealsle assist
