Unhappy Samsung customer

I bought a brand new fridge/freezer in July 2020 and cost me R18000. 00 7 months later and fridge broke on a Saturday. Reported it same day. The Wednesday a technician came out and said the fridge has a leak and all gas out. He now has to submit a report to Samsung to see if they are going to fix the leak or replace it with a new one. A brand new fridge should have been sent to me immediately. How can a 7 month old fridge that cost so much be worked on and not replaced? Its now Thursday and marks 6 days of no fridge plus I lost all my perishable goods in the fridge and freezer. What hurts my heart is that I believe in Samsung and all appliances I buy is Samsung and never had a problem. This service is not okay, there should be an after hours technician available on Standby as we waited till Wednesday after reporting it Saturday. The report was submitted yesterday and I must wait for a decision? The same energy that the store had to take my money should have the same energy to deal with this urgently. I want a brand new fridge and freezer immediately
