Adidas false adverti*****t

I bought shoes yesterday, their system kept on allowing me to buy these shoes. Today I wake up with emails that says my order were canceled with no explanation whatsoever. I just called and they tell me that the order is canceled and that the refund will take 14 days. Why am I being penalized for Adidas system glitch. I made 4 orders transactions and all the time the orders went thru. When I call, to understand Im told a different story.
