Of course they won't.... because this is how Quicken pays for all the advertising... sigh...
Yea, you can try that. I mean, this is the game that they play for this. The get a deposit because they know they are going to overcharge and it would be easy for you to find a better deal elsewhere.... but when you do they are still getting $500 for nothing..... stall, delay, not respond, etc in hopes you just go away. And it works.
It is going to be on you and how much you push on it. If that person doesn't answer then call their customer service line and maybe try sending a message here
