You might want to post this on the Service Discussion board too, not the altcoin one. Who knows, maybe someone make similar mistake with other coins, including Bitcoin. That being said, have you double checked whether the notifications really comes from their official emails? We've seen a mail hijacking attacks in recent years, even popular business got hijacked and their official mail providers sent scam links.
Worst case scenario, waiting is the only option since they probably don't want to process tx individually. Kinda weird that they started to do this now though.
I am certain the email came from them, as I also checked chain activities and see they have consolidate all the lost token across multiple chains into one wallet and also the mail came from their official support email.
Thank you for suggesting the Service discussion board. I will post it there also.
