first ive used bitgo before, and it is very suspicious to me that you are not receiving reset email passwords.
that to me indicates that either they have frozen your account and are investigating because you are trying to double spend a double spend.
or
you are not the original owner of the bitgo account and whoever your trying to steal from changed his password.
Bitgo has a really different login system than most web wallets. Your login to your account is separate from your wallet password. Maybe you're getting the two mixed up and that's why you cant log in.
