Bad sneaker.

I'm so disappointed on Fabiani since I love and support it so much. I've recently bought a new casual brown sneaker from one of their branch in Cape Town and the bottom part is toned so quickly. I'm wearing for the 2nd time and it's sad to see how it is. The code for the sneaker is 20884838. I always support and never had issues with the quality of the item I've bought so far but this sneaker had torn me apart. I can't pay so much for this. I will appreciate if I can get a replacement.
