Star Health And Allied Insurance — mental harassment

I am customer of starhealth since long but i am suffering a lot from day 1 of my 1st claim submission.

They did not care about their customers at all.
Each and every time it happened that they have deducted amount without valid reasons and then

Numerous emails - no satisfaction
Numerous calls - no satisfaction
Numerous tweets - no satisfaction

The company is on peak of harassing their customers, months passes by and the did not respond.

Their customer executives speaks as they dont care about the repo of comapny

I request consumer support to get me out of this troublesome situation urgently.
