Review on Deerma DEM-F628S EU Aroma Air Humidifier, white by Felicja Skrobek ᠌

I bought Xiaomi Deerma DEM-F628S ultrasonic humidifier. I read the instructions and did everything as directed. Bought water for him. Everything was fine, the humidifier ate 5 liters. When I decided to add more water and fill the oil compartment, I saw a crack inside. When contacting the 21st century under warranty, they said that it was not a warranty case! That is, he did not fall, he did everything according to the instructions, he worked 24-48 hours in one week . That is, there is no fault of mine. My guess is why it cracked, it seems so because of the oil. I found that the oil spilled a little on the plastic, after which it became sticky and could not be wiped off. If someone can help to return the money or issue some kind of claim for the return of the goods. I will be very grateful.
