Starbay - Womens Athletic Water Shoes Aqua Sock Yellow / 6 B(M) US

I ordered this water shoe for my water aerobics classes a size larger because I wanted it roomier. The shoe is surprisingly too small! I called the seller immediately when I received them to inquire about exchanging the shoes. No response. I went into the hospital, when I was able to drive, tried to exchange at the store. Told to contact seller again. Back in the hospital, more time waiting to hear back from seller. Finally heard back from them. They want me to pay for return shipping and a restocking fee. I dont feel like the burden should be on me. The shoe runs small to no fault of my own. At this point I am so fed up with the seller and just want my money back.
