Thanks for all the advice, the issue is smartphone i need for work. Otherwise I'd be done with it and sportbet.one seems to get through everything I've tried when relapsing. I get there's onus on myself, but once i make them aware of my issues, then surely the onus is on them to prevent vulnerable people from gambling, such as their website suggests. Only this morning they admitted their self exclusion wasn't working again.
An its not the first occasion this has happened. Anywhere else they would be fined heavily and returning funds that should never have been wagered.
