Lack of accountability and integrity.

So I bought a small bar fridge and I liked it. I plugged it & worked until some days later when I found a chocolate stored inside melted & cool drink hot. The fridge was hot. I just assumed that may the plug had moved or maybe I had changed settings or something, but I didn’t really worry about it because I had arranged for an electrician to change the plug and have the high plug just I did with my other appliances. Time goes by I realise that the problem is actually with the fridge itself because the same problem continued. I then logged a return and the fridge collected after a very long wait to collect it. Days later I get informed that the supplier has fixed the fridge however it doesn’t have the warranty because I had the plug changed. Meaning the fridge was indeed faulty and the plug had nothing to do with the damage and there was no damage made by me on the fridge. By the way I had to send pics when logging the return which I did attach. Anyway, after another long waiting, the fridge eventually gets returned fixed but now it looked liked they were dragging it on a dirty floor because what I thought was just dust turned out to be scratches that have made the fridge look like it 20 years old and it was given to kids to play poppiehuis with it outside. I wrote back to report the issue, and the agent told me he cannot help because the supplier (he refused to disclose) says they returned the fridges in a condition it was when they collected it and that was a blatant lie. These scratches would have been reported just like they did with the plug but they didn’t. Again, these scratches would have shown on pics I sent when I logged the returned and that would resulted to them to not collect the fridge to have it fixed. Its lack of accountability that disgust me because they didn’t even apologise but deny and lie so comfortably and that there’s nothing they will do, so I can’t go jump off the mountain if I want.
