Unfortunately these gambling companies will only appreciate your business if you're on the losing side of the coin. But if not, well they would probably just treat you like shit and may even consider giving you a hard time getting your withdrawals done because of how much money you're costing them just by winning and winning your bets alone. It depends on the bookie too. Some platforms value their patrons very well that they even provide lots of bonuses and promotions albeit losing a lot to these big whales. They got this thinking that the gambler isn't always on the winning side of things, and that they will collect a huge payday eventually from this gambler.
This is quite unfortunate on your end. If I was betting big like you, and not receiving any form of 'thanks' by way of bonuses and promotions, I will also take my business elsewhere and let them reap the benefits of my presence there.
Not all gambling companies, there are few that are generous despite of losing to a player. They value customer relationship and loyal players too. I believe @OP case has something to do with bonus requirements and I somehow think that the bonus has something to do with the amount lost by a player and not by wagering amount.
I actually said that 'it depends on the bookie' too. There are some that remains generous to their patrons because they think that eventually, this whale will have a bad beat and it's best to keep them as a customer.
Haven't heard a lot of bookies awarding bonuses based on the amount lost of the customer. Also, OP didn't mention if those $500 bets posted losses or wins too, so it's really hard to jump the gun and favor the bookie in here. I think Sportsbet.com just wants to get rid of OP because they are losing too much money than they are getting from the OP. But I heard this bookie is one of the largest there is, so it's quite intriguing why they would treat a whale like that.
They actually blocked me from placing a $100k USD bet two years ago on Novak to win the Australian Open. They gave me no reason.
These idiots just lost a whale who brings them a guaranteed 7 figure turnover annually because of their greed. I've had enough of their disrespect and will be moving elsewhere in the next few weeks.
They really just want you out because you are bankrupting them too much
Good luck on your last bet mate. There really are some platforms that don't treat their customers/patrons right even if these same people are giving them huge payouts every now and then. They are only for the money and not really customer loyalty/engagement after all.
