Enchanting Underwater Coral Reef Bathroom Set - Waterproof Shower Curtain, Toilet Lid Cover, Bath Mat, and Contour Mat

There should have been four items in the set, but only one small curtain arrived. That is, none of what should have been there arrived, namely a large curtain, mats, and so on. This is a complete disaster. For a thousand, for a thousand and a half, to receive a miscarriage of a bath curtain is a complete disaster. I will never buy anything again.

I ordered a set of a shower curtain and mats but only the curtain arrived. This is all for 2.5 thousand. Explain why?
