Plz Blizzards, I can't lose the last account I have

Hi,I just try to connect my classic? account in reforged wc3,I try many times but I even can’t reset my password, I realized it may logout more then 3 months, but it carried too many memories to me, I don’t want to lose it, I do remember the
Service region
account name
password
connect email
Please help me to refind it, it’s really important to me, PLZ

It doesn’t work with my account either, I played on it in December. It simply doesn’t work.

I’m not sure if they will fix it.
