Wrong shoe size delivered three times!

I ordered a croc shoe as a gift size 9. They delivered a size 11, not only once but three times! I can't get hold of anyone via phone , only email. I had to eventually cancel the order and ask for a refund, not a credit as I would like to purchase the shoe somewhere else. I was told it will take 2-3 weeks for them to decide if I can get the credit. I'm totally devastated,as they quick to take my money but I have to wait for a refund which is totally their mistake. So very unhappy!
