Worst customer service ever. My Birkenstocks wore out after 3-4 years, so I tried to order the same model and color. I received the wrong color (lighter brown) twice. I returned the first pair and complained, but when I ordered again, they sent me the wrong color once more. I contacted customer service, but they were unhelpful. They kept responding with the wrong colors, and when I sent them the links to the correct and incorrect items, they just replied, "Here is the link, and for technical reasons, we can’t take orders by phone or mail." Despite using the correct link, I received the wrong color both times. Do not rely on Birkenstock customer service—they can't differentiate the colors of their products and won't help resolve issues.
