Samsung blatant disregard for consumer rights

I bought a Samsung Fridge via Hirsh’s on 9 August. The fridge is defective in that the fruit n veg draw freezes. Samsung sent a technician out who changed the temp settings and took pictures of the freezing fruit and veg. This has not rectified the problem. I asked that Samsung to honour the Consumer Protection Act (CPA) and replace the defective fridge but they want to send yet another technician out. The CPA is clear regarding defective products and my rights (refund, replace or repair at the consumers election). No one in their call centre can answer any questions and instead choose to pretend that the line has cut out. Samsung clearly does not respect consumer rights or the law.
