Defy is the worst

We bought a auto washing machine on the 16th of October 2021, they delivered on the 19th. We used the machine the very same night and when it had to drain it didn't. We reported the matter there next day at House & home where we bought the machine, they then noticed Defy. Defy sent out a mechanic on Friday, he concluded that its a factory fault and that the machine needs to be returned and given a new machine. We have contacted Defy with no luck, here we are with a new machine that I can't use. I am very disappointed with how they are handling things, we bought this machine cash with no issues.
