I bought this AC just 2 years back ( 50k bucks). i roughly used for 6 months only.
technician came after 2 months after complaint.
first technician asked 1000/- for visiting.
second tech, said DC motor problem. it costs 4800/- he said. i checked with regional manager belongs to Vijayawada. he also said same price with no warranty.
as i am staying in Hyderabad i tried to speak with regional manager here he said 1800/- without warranty. and i bought it at hyd loc.. but this motor was used one.
third technician came to fix the motor, he said that PCB problem not the motor. then i again came back to hyd, with motors and PCB. here after two days they said PCB has to replace and it costs around 18000/-. i do not understand whether these guys are human beings/customer care team or terrorists to us. i am still bothering about this issue, problem came in March 2018.
