MakeMyTrip India — no response, no notification of flight change and no refund process

i am only looking for support with my booking id nn[protected]?
My mother rekhaben shroff has flight booked on 10/10/2020 and pnr is jj3cv.
Upon checking with airindia they advise that this flight has been cancelled. However, makemytrip haven't notify me about this.

I am unable get connected them via call centre, email support, facebook messenger support and online chat support.

As first source of attempt, i have selected option and insert my booking reference number and ivr says we are unable to help.

As second source of attempt, it doesn't recognise my input when i am selecting options. I tried multiple times it was the same.

As third source of attempt, i have used my wife's mobile and connect with new booking line it was successful. A person told me to get assistance he is going to transfer my call to relevant department and transfer me back to ivr system again.

As a fourth source of attempt, i tried to reach to mmt by facebook chat where i got response initially and then after no response.

As a fifth source of attempt, i have tried to connect them via their online chat support called myra and that ends with saying unable to help.

During my multiple attempts to contact with makemytrip i experienced following:

Agent's voice is not clear.

Agent is having poor connection.

Agent disconnect the call after putting me on long hold. Additionally, no email support has been listed on website.

Please help me resolving this issue.
