Query: Not Brown Nubuck!

The shoes pictured are brown nubuck(suede)-just what I wanted. The shoes I received were brown leather - not at all what I wanted. Shoeflake was very prompt in refunding my payment, but I was very disappointed not to get what I ordered, and annoyed by the waste of my time involved in reporting the error, sending back the incorrect merchandise and waiting for a refund.
