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.
Writing here is not a bad option neither isn't it? I mean if you have a secret problem that you can't share here that means you should be writing the support, they are very active and they would help you out (this is a company that paid 6 million dollars for sponsorship, think about how awesome their live support is) but if it is something that is not a secret or a problem you can share with everyone that means you can write here as well.
In any case live support is still better because its "live" support after all, whatever problem you might have they would fix it in matter of minutes there. I personally never had any issues (thank god) but if I did I would totally use their live support.
Barça is looking like favorites tonight, I may end up betting on them as well.
