Estee lauder worst customer service ever

I purchased a product online on sale. It was a wrong color. I contacted customer service the day of recept and was told I could take it to any Estee counter and exchange it.. I was then told I could only exchange it online. When I contacted the online customer service, I was told there is no exchange or refund on sale items. This is worst customer service I've ever encountered. I've been a customer for over 10vyears never again .I will be taking it up with the correct authority.
