Like Oshosondy said, Bet365 withdrawal options depends on your country of residence, so depending on the country where you live, some options might work and some might not, I will suggest you contact their customer support for proper guidance.
If a bet365 user is having money in his account already, he can click on withdrawal to see the withdrawal option that are available. I noticed that the withdrawal options can be lesser than the deposit options. Like in my country, only wire transfer was available the last time that I withdraw money from the gambling site, but more options are available for withdrawal from some another countries, especially in country like England.
I`m not a bet365 user but several times i saw the problem that it is impossible to withdraw money if you haven`t deposited money in the same way. May be the OP just need to deposit some small sum firstly to prove that it is his wallet?
The same time @Daltonik posted enough choices to withdraw.
This is a common requirement that we must do to withdraw money because it also happens in crypto casinos that we often use to gamble.
But if I were him, I don't want to withdraw the money directly to my bank because the bank will check the transaction first and will make sure that everything is according to the applicable procedures. If your country allows gambling, I think it will be safe and the shipping process will continue until it is finished. But if not, the bank may ask a few things before they can complete the process. Maybe sending the money to Paypal, Skrill, or some other method is safer than sending it directly to the bank but I don't know.
But indeed, asking for customer service is the best way not to violate their rules.
