Central Board Of Secondary Education [CBSE] — No response and answer on migration certificate application (applied urgently)

I have applied for a hardcopy of the migration certificate on 4 Feb. 2022 for my class 12th (passing year 2021) and I still haven't received my migration certificate though I applied for it urgently and in your cbse guideline point no. 6 (https://www.cbse.gov.in/faq/dup.htm) its clearly mentioned that if certificate is required after two days ( excluding holidays)…for reference click on link
I have paid the fees of Rs 850 including all the extra charges in the fees itself and I still haven't received my certificate so I request you to tell me the status of my migration certificate as well as the date I will receive it.
I have called cbse many times and tried to call the regional office that is (Allahabad) Prayagraj but the call is never answered no matter how many times I call.
please resolve my issue as soon as possible as I really need my migration certificate.
its been 10 days since I applied for my migration certificate.
