Worst Service Ever from Defy!

I bought a Defy fridge/freezer at Makro in December 2018. The freezer seal came loose and Makro assisted to log a service call with Defy in beginning April 2019. It is now two months later and I am still waiting for a technician to come out. I have also called the Defy call centre at least 4 times and personally spoke to the Call Centre Manager, who promised to send out a technician within a few days. That was three weeks ago and I am still waiting and have left two messages already for him to come back to me, but my call has not even been returned. My job number is ********** . I wonder if anyone at Defy values customers.
