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.
