HDFC Bank Ltd, Home Loan — NOC for co-applicant name change is taking forever causing financial loss

Address:

25/8, Diamond Harbour Rd, near Janakalyan School, Kolkata, West Bengal 700008

I have an ongoing Home loan with HDFC Housing Development Finance Co bearing the account number[protected], my father expired on 31st Nov 2020 who was also the co-applicant for my flat at Riverside, HIlands Greens, Batanagar, Maheshtala, West Bengal 7000140, now i submitted a written application to HDFC Housing office at HDFC LTD., Merlin Estates, 25/8, Diamond Harbour Rd, near Janakalyan School, Kolkata, West Bengal 700008 on 04/03/2022 requesting for NOC and change of co-applicant name .from my father to my eldest brother . Since 04/03/2022 i haven't got any update neither through email or phone about the status of my application . It has been over 2 months it is pending and due to this my flat handover is delayed .

This causing financial loss to myself to due HDFC delay in producing an NOC which i think should be provided maximum within 2-3 weeks time.
