Defy Microwave

We bought a Microwave in December 2018, April 2019 it stopped working went in for repairs and only came back end of May, the middle of June it did the same thing then went in for a repair the guy replaced the "board" and came back. July it started the same thing and we have been back and forth now with this issue and it is still not fixed! then tell us they will fix and deliver it??!!! for us to only return it again??!!! this service is pathetic and the quality of the appliance is too geez what an inconvenience.
