After taking a glance at the market rules I found this, so you may have a chance at getting refunded with your item:
E) In the event of a user's mistake resulting in a market bot purchasing their item, they must be refunded in full by the bot owner (provided the bot owner is notified within 48hrs of the purchase). Note: We consider it a mistake if the item is listed for sale on the market with a price under 25% of its market value at the time. This is subject to the discretion of the market squad in the event of unusual circumstances.
If anything, I'd recommend making a thread in the scam reports section and see what happens as I am not sure if this rule only applies to market bots.
