Medi Assist India — reimbursement claim no. 15244322 not yet processed

We have submitted all the original claim documents on 04 sep 2017. Afterwords on 12 sep 2017 we received message "we regret the delay in processing of your claim no: 15244322. This is being reviewed and you will have an update shortly", however we have neither received the reason why delaying nor claim amount. We are not able to understand why so much of time required to disburse the same. Current status is showing as "under process" i don't know why this claim is stuck in the system. Please look into the issue and do the needful.
