Panasonic — Free warranty service not performed by Panasonic

Address:

Panasonic

Service lodged three times and local service center not coming and closing the service call by saying customer has no invoice.
Fed up with false closing
Worst is.. Panasonic itself closing the service call without reconfirming from customer means me.
If after sales service is so worst then I would like to return my AC back to them and want the compensation of harassment done by Panasonic and its service vendor.
