Beware of Hirsch's after sales support and returns policy

I bought a Samsung microwave from hirsch's Milnerton. Within 1 week the fan stopped working, the turntable stopped turning and the light was dead. As a result, the microwave would overheat and switch itself off. I returned it, hoping to be able to replace it, but was told it will have to be repaired (I'm sure this is a breach of the CPA). I was contacted after a week and told that the microwave was repaired. Only the light was repaired. So I took it back a second time, requesting a refund. I was told the microwave will have to go for assessment again. After 2 weeks, and me having to provide video proof of what I was experiencing, I was informed that I could get a credit, not a refund (this goes against Hirsch's returns policy and the CPA). I will use the credit on something that is not likely to break, but I will never support Hirsch's again.
