Clarks — Dissatisfied with faded shoes from a familiar brand

Clarks team
My name is Kannan residing at Velachery, Chennai. I bought Clark’s Men navy leather loafers-10 UK from Amazon. herewith attached is the proof of invoice copy and shoe pics for your reference. As I was stuck in lockdown I couldn't wear the shoes for some months. Now I ‘am really shocked to see that the blue color has changed in some places after using the shoe for a week. I have used many brands in my lifetime. But this is the first time that shoe color is changing in the reputed brand which I cannot digest. Please give a replacement for this at the earliest.
Awaiting your favorable reply to my complaint.
