Crocs won't take responsibility for a mistake on their online store. I don't want a discount, I want my crocs.

I've always been a huge fan of Crocs - not anymore.Bought Crocs at a discounted price for me and cousin(its her birthday month) on the 21st of September. I was so excited, I thought I had scored a bargain, only to sent a refund a day later. When I called customer care to make an inquiry, a lady by the name Karen told me it was not the companies fault, a third party company that runs their website didnt update their stock accurately. She told me greatful they gave me a 30% discount. Im truly disappointed and feel ****** and ****med.WHY MY ORDER?. Why cant Crocs take responsibility for the inconvenience instead of me. I dont want a discount, I want my pink Crocs. :(
