Thanks for reply. Their terms and conditions state:

We introduce a crucial first step for users considering a break from gambling. Upon receiving an email request for account closure, sportbet.one doesn't just snap the door shut. Instead, we initiate a 24-hour cooling-off period. During this time, the account and any linked accounts are temporarily disabled, putting a halt to all gambling activities. This pause provides a moment for reflection, an opportunity to consider the decision without the immediate pressure of gambling options at your fingertips.

I follow this and get nowhere so its very frustrating, as tbis is me acting responsible following a relapse trying to put protective measures in place and all they do is make it difficult.
