Sorry, but why do you expect the OP or any other casino representative to credit you those $10?
You have just signed up, what makes you think they owe you anything?
As far as I can see, you are part of an alt farm trying to take advantage of such events.
Good for them that they haven’t satisfied your greedy attempt.
If you need free money then you need to look elsewhere.
That kind of gambler are the ones who can easily be duped by fly-by-night casinos because they are after for the perks and not really checking the conditions attached to it.
