Hisense Glass fridge

I was sold a Hisense glass fridge that has scratches on the inside of a glass and returning it was a mission they didn't want to take and I was told they want a box. I threw the box away because I was advised that the technicians will come and have a look at it and they never did. I had ro accept a fridge that was on display because they didnt want to give me a new fridge bare in mind that I bought it cash for R13000. 3 weeks later they send the display fridge I am so disappointed and would never recommend anyone to go buy there.
