Is Scarlet Darkness a good brand ?

I'm seeing very mixed reviews. Apparently their products are good quality, which is pretty unanimous, but then some people received their orders and all is good, and some people are complaining of never receiving anything, and the customer service is not answering either.

So I'm really unsure if I should buy anything, even if I fell in love with at least three of their dresses.

Finally, I'll add that I'm French, if it change anything to the question (maybe Scarlet Darkness is really good in the US and not anywhere else, idk). So I will also apologize for any mistakes on my part, English is not my first language.
