Recurring faults and poor service overall

I have a consistent fault on my chest freezer that the store (Makro Carnival) is failing to fix. I have requested an exchange or a refund, but no, all that Disebo (Appliance manager) is telling she will address the issue with KIC. I find this unacceptable as a customer, because the warranty is nearer. Maybe she is trying to push it until the warranty is finished, as she said Makro do repairs up to 4 times at least. I mean what kind of service is that? Is she implying that they selling faulty appliances? Such tactics are distasteful for a big store like Makro. By the way from the same stock I have been refunded on my TV, double door fridge, to mention but a few. With such recent developments, I'm profusely withdrawing my services and will edge everyone around me to do the same.
