Clarks — shoes have changed colour

Address: 560042

I had bought a pair of patent leather heels from clarks a few years ago. I recently open dilip the box to wear them for an occasion and they have changed colour and become a horrendous golden colour from a beige. This is unexpected especially when kept inside a box, i live in bangalore and there is no humidity etc for thai to take place. Your shoes are expensive and this is least expected. Pictures are attached. I[censored] look on the side of the shoe, thets the original colour, beige. I want a response on this immediately.
