Aditya Birla Health Insurance — Claims pending for 100 odd days

I submitted claim on April 19th, from then Aditya harrassed me with this doc that doc, inspite of submitting everything that needed, they fail to reimburse the amount that's due for customer. They don't stand by their rule of clearing the amount in 30 odd days it's been close to 100 odd days and no one knows what's going on why there's a delay etc.
