Query: NOT the real Deva Curl

I've been using Deva Curl faithfully for almost a year but I've been purchasing it at a local shop. Having now found it on Amazon for around 40% less, I purchased it and I am so disappointed. It is NOT the real Deva Curl. My hair color is now fading quickly, unlike when I purchased it locally. My hair dresser noticed immediately that my color isn't lasting like it had been. I don't feel like it's working at all any more. I am so disappointed that I got such low quality knock off merchandise over Amazon.
