As far as I know coinbase wallet usually not asking for verification if there is nothing suspicious (don't know if they implemented new rules recently). From where you have sent your fund any other wallets or gambling? You should submit clear copy of your documents. I have verified coinbase and it was to almost a minute. However, if eventually you fail to verify then delete your account. During deletion they will ask for withdrawal your funds. So you have to withdraw your fund on another non coinbase address. Then you might create new account with new emails and try to verify your account before make any deposit. I will not encourage you to use any web wallet for store your funds.

I am bit confused if OP talking about pro coinbase (exchange). I never used it.
