Im not sure social media could be assist as fast as possible in quick response. If you've limit on sending a message to steve for asisst your problem or qeustion. You can try live chat (live support) on website, they will be best way to break your limit.
Their social media accounts are not always active, they are online if they have to post something. It's better to contact them through the site only and they have a 24-hour active support agent. You also need to know that Sportsbet has an Instagram account and they are always active there by posting stories.
