Panasonic — after sales service (ac 1.5 ton)

Ref : grievance number: 1839393 it is not fare panasonic it selft declare its big problem need to re-installation and asking for[protected] rs, once we register complain against panasonic in consumer help, panasonic declare it's not an issue everything is ok not need to re-instaliation there is no problem.. I cant understand how can panasonic cheat with customer, i dont want to fight but i want put under observation for 3-4 months at the time of actual using, but at that time warrantee will be over, how can we check panasonic's solution?? And how can panasonic close my complain without take any action?? What ever panasonic attached sheet which is not under my sign, under sign by house wife and she dont know any technical things, if panasonic is confident on their solution then please increase the warrantee for 3-4 month so i can check it.
