Damaged items when moving

I booked this company to move my furniture. My fridge was dented and sc****d. My headboard was also damaged in the process of moving. I have communicated with the company and the only response I received was that the reason for the damage was that the headboard had to be hoisted and the company was not aware. I realise that this is valid but the fridge was not hoisted. The company was made aware that the house had 3 flights of stairs so I dont understand how them damaging my fridge was justified.
