Maruti Insurance — policy's hard copy not received

Hi,
I renewed my insurance policy on 20th april and till date, i didn't receive its hard copy. Although i was informed that i will receive its hard copy soon.

I wrote an email regarding this so one of their executives told me that they have forwarded my request to my nearest center and i will get the copy soon. But it been a long time and i didn't get any information that when i am getting my hard copy or any track id.
My vehicle is:- balenodeltapetrol
Number:- up16bv9974.

Till date my complaint is not resolved and their customer care executives are not replying properly that how should i proceed.
