Panasonic — Split AC

Address:

Raj Nagar extension

I had purchased inverter split AC six years ago. The AC has stopped functioning. I have been in continuous contact with the company customer care and service centre but to no avail. They are telling me that the company has stopped producing the spare parts which are needed. How can a company stop providing the split parts after 5-6 years when an average life span of AC is claimed to be 15-20 years.
It was an expensive AC and the service centre has asked me to buy a new one as this will not work.
In this record breaking summer this harassment is causing health issues and mental stress.
Please help
