Council For The Indian School Certificate Examinations [CISCE] — TC request from St Stephen's School Birati

Address:

Nimta, Birati, West Bengal

St Stephen's School Birati is not providing the official Transfer Certificate (TC)

I had request the School to provide me TC for my daughter's admission to Grade 2. She completed Garde 1 from the above mentioned school and started Garde 2 in Dubai. I need the authenticated TC to complete her admission in Dubai school.
Initially, the school issued one TC without proper channel in February. When I submitted that TC to Dubai, I discovered that the TC should have been endorsed by Delhi headoffice as per the guideline from the centre. Then I requested again to the school for TC endorsed by headoffice. It's over 2 months, I haven't received yet. I have attached the emails for your reference.
I need your help to complete her registration in Ministry of Education. Please let me know how I can get the TC when the particular school is not supporting me.
