The difficulty here is that, karmic has a point where he wants his money, we can all relate to that, after all we know how much 100 bucks could mean to all of us, hell 100 bucks would help me not have any economical issues this month and cover my credit card expenses.
However, at the same time we all know how little 100 bucks is for sportsbet, these dudes literally sponsoring Watford, a premier league team. We have no idea how much the sponsorship is for (btw, can sportsbet share that? Like how much you guys are paying for being a partner?) so we all know 100 bucks is literally nothing to them and they could just simply pay that as a gift, hell recently they did a 1 btc (10k at the time I think) giveaway for just being on the website, no requirement to even gamble. So I think this would be closed very easily, not a big deal, just some misunderstanding.
