Municipal Corporation Of Kanpur — Death Certificate not issued

Dear Ma'am,
I have applied for death certificate of my wife late Shashi kala Shukla on 15/05/2021 due to pandemic. She passed away on 01/04/2021 in Government hospital and we did her cremation on 02/04/2021 at Bithur Shamshaan Ghat. I had submitted all the related documents but still i do not get her death certificate from Kanpur Nagar Nigam. I visited 4 times to get it but your representative did not give any satisfactory answer. They used to say that it is pending. How it is possible i do know. Although some person got the death certificate of their loveones, and he applied for this after my application.
Please help me to get death certificate of my wife.
