Received incorrect item - which is Non Refundable / Returnable. Their error, not mine.

Ordered a Foundation and a Mascara. Received a Foundation and a Blusher - which they are saying is Non Returnable, Refundable. I contacted them the minute I opened the Box, sent all the Images through as requested. I have been pushed from Fayzel, to Avela, to Nariema. This has taken 3 days. Nobody responds.
