Bad service no value for money

Good evening, we are so disappointed we bought a fridge that is still under warranty and it doesn’t work anymore. Hisense keeps sending out a guy to fix the fridge but no joy and he keeps coming after hours every time I call Hisense they said he replaced a compressor that was false then they said we just have to wait. He is unable to fix the fridge that we paid almost R20000 for. This is such a huge inconvenience especially that this guy can’t fix it and he keeps coming after hours when we are busy with home duties kids cooking homework it’s hectic after work.
