Hi Sheila,

I'm so sorry to hear that you received mismatched colours on your Birkenstocks! We would love to rectify this matter for you, but we'll need more information. Could you please send your query to our customer service at adriana@spartoo.co.uk so that we may be able to find your order and help you?
If your order was shipped to the US, we don't normally have free returns on orders. However, I'm confident that we can do something to compensate you for the return and the hassle you have experienced. Please get in touch with us right away! I will also pass along this message to the customer service, but as they do not have your full name and order number, it is best if you can contact them directly.
I do apologize once again for the inconvenience, and we hope to hear from you soon!

Sincerely,
April Buchanan
E-Marketing Manager Spartoo UK
