Life Insurance Corporation of India [LIC] — Tech Term Insurance bought on 31st July but policy not issued

I had purchased LIC's Tech Term Insurance policy on 31st July 2021, paid Rs. 16488 as half year premium, underwent all medical tests and uploaded all relevant documents, even after 3 months policy is in proposal state (Proposal No. 13059).

However I never received any proposal status update. I mailed to many different email addresses asking for progress, I didn't receive any reply except only once or twice after calling published contact numbers hundreds of times as they are busy all the times:
[protected], [protected], [protected], [protected], [protected], [protected], [protected]. If at all I reach any of these number, the officer says that they don't have information about policy bought online, they have information of policies bought offline.

Finally, I mailed to complaint/grievance email id [protected]@licindia.com found on your portal 15 days ago and as usual I didn't receive any reply.

Please help.
