New Freezer not working

Bought a Freezer on the 2nd of March 2021, tried to plug it on the 3rd of March 2021, freezer was not working, no power and not freezing. Phoned repair center, 6th of March they inspected the freezer and confirmed it's not working. Technician advised to recommend for a new freezer as I told him this freezer is new and I'm not comfortable with repairing a new freezer, I would have bought a second hand freezer if that was the case. Phoned on 9th of March, no notes have been updated on the system, phoned on the 11th, my complain still to be reviewed, phoned on the 12th and was told to take the freezer back to the shop. I advised the consultant: I'm not working, had to save for a year to buy the freezer in order to start a small business, R400 was paid to hire a van to transport the freezer from the shop to my house, if I'm told to take it back, where would I get R800 to transport the freezer from my house to the shop and back with the new freezer? I feel I'm being exploited now, can DEFY please exchange my freezer in order to to start a small business and be able to provide for my kids. Case no. ***
