Poor service

Just want to express my absolute frustration and disappointment with Samsung repair division. I bought a fridge at Hifi corp Mall of Africa and has been malfunctioning since it was bought in December 2023. To date repair calls are being logged left/right/centre. More than 3 different service centres have come out to repair it, compressor replaced, gas refill and all but the fridge is still malfunctioning with 4 to 5 different technicians having looked at it. Escalation was sent to Samsung regional manager by the name of Dan who had called me and promised me to give him a week to look for a replacement fridge or refund, now he’s blueticking me on whatsapp and ignoring my calls. Hifi corp mall of africa manager said they cannot process a refund or replacement without his approval. I’m disappointed and disgusted by the behaviour of such a big reputable company. My next step is to go to the consumer ombudsman. They will pay for this distress they have caused me.
