I'd just call them back in a few hours. Don't call them every hour or whatever, that can drive a dealer nuts! But call back later, or ask them when a good time to call back is.

That's the only way you'll know if any is coming through. Just say, "when should I call back?" and viola!

Don't hound them though, especially if it's for a small amount. Bothering a dealer all day for a gram or 2 will result in them in getting annoyed, and not wanting your business.
