Consumer Redressal

I have bought Carrier Split Air conditioner 6 months back.However since day 1 i am facing some sorts of issue. Sometime it gives gas leakage problem, some times it gets switch off automatically and now the display unit of device has stopped working.I have logged complaints several times but nothing commendable is done. Display unit of my device is not working since last 2 months, after logging complaint an engineer visited my place and during his 2nd visit he took that part with him to get it replace as it seems to be faulty one. Its been more than one month and that part is still not replaced. It was new AC which i bought and i am still facing those issues My complaint number with Carrier is 91110081 and it was logged in the month of Oct. Regards Summit 9899998516
