Central Board Of Secondary Education [CBSE] — I am complaining about the scam of duplicate marksheet

Address:	Chennai
Website:	cbseit.in

On 17th August 2022, I placed an order for duplicate 10th marksheet on CBSE website, I also paid the charges but till date I haven’t received it, I also marked it as urgent delivery as it was needed for the passport, I also mailed the concerned persons but I haven’t received any updates.
The phone numbers mentioned are never working and not updated also.
The fee on their website was 500₹ and they have charged 850₹ to me for which they didn’t provide any breakdown details.
My concern is I want this marksheet as soon as possible because I already applied it 1 month back.
I feel sad because such a huge department is so so careless and ignorant.
