I got scammed into paying for fake a advertisement. How do I go about getting my money back from Chase?

[Hodgson]

My husband is a new personal trainer. This woman calls claiming to be with Fitness Magazine and said that she is looking for ONE personal trainer to feature ON their website. We paid $250. She guaranteed us 10,000 views. After 17 days there is finally an "ad" except it's on this crappy low quality datasphere website where they literally just copied (like they have some generator) my husbands website. I looked back through all our emails and turns out the people claiming to be with fitness mag are with datasphere... looked more into it and read a lot of reviews of them saying the same thing they told us for other ads like scenty etc. This advertisement is completely fake and not at all what "the contract" states.

How do we go about getting our money back to our Chase checking account? I know it's a little tricky because we gave them our information (can't believe we were that stupid and believed everything). I just realized everything today, which means I do have time to try and get any information that I can from them. But I can 100% prove it's a scam. Anyone have any advice who have actually worked for a bank??
They claimed to be WITH fitness magazine, but fitness magazine has never heard of them.
They gave us fitness magazines url to look at where we would be advertising
We were gauranteed 10,000 views in the Portland area per month but the ad was published 5 days shy of the first month
The ad is not on fitness magazines website and is just a computer generated 'business profile' - there is no actual ad
The contract states an agreement between my husbands pt business and fitness magazine
This is straight up false advertising and fraud
