Disappointing service from Berlinger Haus re Pots decoloring.

I purchased my children a set of beautiful pots. Within the 1st month of use these pots became ugly - lost color. we did email Berlinger Haus, but they have not even bothered to respond back to us. In October 2020 we sent them the photos and no luck. Very disappointing as the pots are lovely but looks disgusting!!!! So I will NOT recommend anyone buying these pots.
