He fixed my AC last year, saying he is expert in AC repair, and considering his confidence I trusted him, and paid Rs. 5500 along with 2 years warranty. First he fixed the machine in around 1 month, and after installation it failed within month. Its been 1 year, that I keep calling him, and he just ignores, and with great confidence, says, that he will send a guys next morning. I travel out of Delhi too much, and hence this follow is ever going, and also the AC is secondary, and hence it is not a pain or must, so I keep on doing constant follow ups.
