Mdindia Healthcare Services — Regarding delay in processing of authorization approval

Good morning sir/madam;
My mother named mrs. V. Jayalakshmi has been planned for hysterctomy (Surgery). Preauthorisation sent from maruthi hospital;cuddalore ;tamilnadu on 19/8/2020. When i called tollfree number on 20/8/2020 they said they did not receive anything from maruthi hospital but on further enquiry they got the mail on 20/8/2020 at 1.45pm. But from the hospital side they called on 19/8/2020 to mdindia insurance office they said they got the mail and they are processing.
Till now no response from md india insurance side. We are waiting here for surgery for 2 days. Till processing is going on only saying from insurance side. What is happening there in your office one person is saying they recieved mail on 19/8/2020 and the other person is saying they did not received any mail. What work is going on there without any communication between office staff???
Now we are suffering because of yours fault
