They delivered a damaged freezer ***2

We bought a freezer online from Hirchs on the 28 of November and when they delivered it was not working. We called and sent messages for assistance and sent messages they said at least 4 working days for a technician but it took longer than that, they came and told us the part that makes it is damaged and it will take another 4 working days to order the part and that it is damaged because the freezer was in the shop for too long, not new. We asked for a refund and they said they will do it, after following up for days from Hirchs in centurion they tell us that we don’t do it through them since it is online we need to do it online. I have been stuck with a freezer for over a month with no help and when we follow up we are told to wait, not helpful at all. I just need a refund, I need to buy another freezer. I had to ask the neighbour to keep my stuff who has gone for the holidays.
