Air India — didn't received my e-ticket yet, despite of booking online from airindia website

Yesterday, i have booked a non stop flight ticket online from airindia website as a guest user for 24 oct 2019 from mumbai to delhi.
But after final payment also, i have not received my e-ticket yet on mentioned email provided while booking.

I am fedup of trying to reach customer care support many times, but it is busy all the time. And not also any response get from email yet.

Why the emails and contact numbers are mentioned if your staff is not capable to respond.

Such a irresponsible airline.

Kindly send my e-ticket on email.

Ticket booked for - kunika aggarwal

Thanks
