Ordered a pair of Sanuk yoga mat wander flip flops today; I entered the correct shipping & billing address. When I received my confirmation email, the shipping address was incorrect. I called customer service to change the shipping address; after holding for a few minutes, I was told they could not change the shipping address, & would have to cancel the order and place it again. I said that was fine; after holding again I was then told that the flip flops were all gone, and did I still want to cancel my order. After going back & forth, they continued to say there was nothing they could do; at that point I was so frustrated I told them just to cancel the order and issue me a credit. Extremely annoying!
