I bought a fridge and they sold it to another customer

I bought a fridge from this company and on a delivery day it never arrived. I contacted this company and they said that unfortunately my fridge was sold to another customer but they promised me to deliver another one next day. They never made a notice and I think this is not a good service. Well but the worst thing is hat I had to wait for my fridge more than two weeks and they refused me in a partial refund or in a discount for all these troubles. Do not use their services!
