Customer service is waste and useless, same technicians, they come to spoile AC they don't know their own work. I had problem with censor and these technician come and fill compressor and go. Then I searched AC technician outside and now problem is little bit solved, not completely solved. After sale service is waste. Electricity Bill come too much, even if I run AC in night my bill charges get up to 2000/ and 2500/- extra.
