Medi Assist India — insurance reimbursement

I have submitted reimbursement claim. And all required medical reports. Despite that they told that they haven't received my documents and closed the claim. When i call customer care everytime they will give some wrong reason. Also they have asked my sugar reports after 4 months i have raised claim. Its worst insurance i have ever seen with worst service.
There is no proper response. Even their sms service is worst. They have asked us to send sms to[protected]. Even now my claim status is showing as work in progress when even i will send sms to this number.
I used to call helpdesk very frequently. Despite that they are not specific about the reports they want. I have already submitted all my blood reports, but they reported that they have not received my documents. I have the courier number which shows that my documents have been delivered to helpdesk on time. But when we call helpdesk they reported that they have not received courier and my documents.

This is the worst insurance with worst customer service.

They are very ridiculous to process our claim and worst tpa.
