Hi-Fi Corporation took my money but dont deliver a new unit

I bought a brand new washing machine online on 22 February 2022. When the machine was taken off the courier truck, water was running out of this brand new unit. Obviously I refused to let the unit into my house. Hifi Corp are now try to cheat me with a story of the unit was tested and that is why there is water in it. What a lie (bu44**** story). They think I am an idiot. It is obviously a previously returned unit they fixed and now trying to sell me as a brand new unit. I still do not have a washing machine and they have my money. Now I am forced to pay a luandromat to do my washing.

My online complaint ref no is ***
