Tough luck man. Accept your loss and move on, they will never reimburse you back $7000. If you get them back, consider yourself very lucky.
Next time be more careful when you type the amount.

There is huge chance they will give it back as they want to keep a good reputation and make it even MUCH MUCH better.
Such advert - "They gave it back! I love this company - you can trust them! No scam for 100%"

If I would be them - I would do that.
