Not fulfilling their orders when they make pricing errors

I had purchased a Corsair H100x radiator cooler as advertised for R1 and they just sent me an email to state that it was a pricing error. They need to fullfil this price to whomever bought it and fix the pricing afterwards. Not mail a customer to refund. I want my cooler. I'd appreciate if anyone else experienced this and can help me get what I paid for and what was advertised. I took a screenshot of the item with the advertised price prior to them changing it.
