Not happy with Iwye

I reported my washing machine to Iwyze that it was coming up with an error but no water leak. They first sent out an assessor to look at it and then they said they needed further investigation on it. It was then taken away, 2 weeks later I get an email from Iwyze stating they going to replace it. 1 week later and nothing is happening. I then enquire about it and I was told now after they received the report from GW Tech it stated normal wear and tear, that caused this problem. So what happened a week previous when they sent me an email stating it was going to be replaced. Also they bring the washing machine back and now it has a major leak coming from underneath the machine. Which was not there before they picked it up for assessing.
