Poor Service follow up

Our Samsung freezer is not freezing our stuff, and I paid the service fee and confirmed payment. They told me it would take about 3 days. It is now a week and three days. I called after that to find out that it could take much longer since I had to wait for a technician to be in our area in South Africa. Furthermore, it's now a week past, and there is no call or follow-up, and I sit with a broken fridge. They are destroying the name of Samsung products with this ghost town service. I would opt for another brand but probably get the same horrible service in this country.
