The reason your account was not verified but decline could be the ID document used (I mean the ID card). Is it drivers license, voters card, national identity card or international passport. Make sure you have a valid ID card that support international verification (not only local purpose card). But I think it should work if you used a valid ID card.
Also, is your picture clear on the ID document and nothing about it is fading already.
The info above is the most accurate reason for not being verified, Binance verification team is very active and typically verified the user application within an hour as long as the document he submit is valid and clear.
Contact there live support via app or email them. There support is very responsive. You just need to wait for the queue list to clear but its not that long. AFAIK, They are sending an email about the reason for the rejection of KYC application maybe work on that.
