Wrong size, no return, non-responsive

I ordered shoes from here for my wedding and gave size and explicit measurements. The shoes came in and were nearly three sizes too big - and it was too close to the wedding date to replace them in time. Still, I wanted my money back, so I emailed about a return. I NEVER got a response, even after emailing several times from different accounts. I have to assume he is simply ignoring me. Now I am stuck with a pair of $300 shoes that don't fit. Total waste, very unprofessional.
