Superlative Serum Phi

I bought the entire set of Auteur products in a big orange box. I intended to give it as a gift, it arrived missing a cleanser and was replaced with a mask that eas already in the box .so i had to keep it i didnt want same items in the set . I contacted customer services , they told me they would add it to me next otder. I orderd phi again & my usual products- no missing item was added to my order. Contacted customer services again they have not replied ….after 5 days- how easy would it be to put this right?
