Génifique Ultimate Serum Set - Limited Edition

incorrect item received

However, upon opening the package, I found that the full-size serum is 30ml, not 50ml as advertised. I specifically bought this set because it was clearly stated to include a 50ml serum. I am not interested in the 30ml version. I would like to understand why the item received does not match the description, despite being promoted with the original value based on a 50ml inclusion.
