And the amounts you mention are not at all inviting to scam players. If it were a few hundred thousand dollars, the story would make more sense.
The amount doesn't matter in any scam accusation no matter how low it is. However, the OP is raising a scam accusation in regards with the technical difficulties on the weekly bonus link as well as unfair amount of weekly bonus provided.
Since the casino or platform mentioned is a reputable platform, OP must provide any evidence to support his claim such as the screenshot of broken weekly bonus link, conversation from customer support, estimated weekly bets and bonuses, and any other evidence that will back up his accusation to the said platform.
Something which is going to be difficult to prove, after all stake did not really scammed the OP since this is a bonus problem and there could be many explanations possible, like a change in the size of the bonus to old clients, technical difficulties, the OP not qualifying for a bigger bonus due to the games they played during that week and an interminable number of reasons that could be used to explain this issue away, so unless he can demonstrate that whatever bonus he was to receive was in fact stolen by someone at stake there is not much of a case here.
