Aqua Care Insurance — AMC and Service defaulter

All complaints below registered for service and filter replacement, is true to my experience too, .
AMC period 3 yrs
No service ever provided, 1 year got filter replaced after continuous follow up.
Later no response even for annual filter replacement.
Not attending calls,
Spoke rudely once when requested for service.

Is this an official site to register the complaint against this company to get AMC money back?

Thanks
