Lost BTC - can't access 2FA

1M Ago
Just wondering if anyone has advice. Essentially I've an old wallet with BitGo, for which I know the password but the phone I used for 2FA is no longer in use. Unfortunately I seem to have lost my keycar, wallet address, don't know the last 3 transactions (back in 2015) and I don't know how much specifically is in the wallet so BitGo won't reset my 2FA....has any had similar and found a solution?!
