Dishwasher in worse working order

My LG direct drive dishwasher needed a new motor. The guys took it away to do this. It was returned and I paid for it. It had been very badly damaged on the top (as it another machine had been put on it) and the door was dented. This was the 16th of August 2017. After washing for the first time my kitchen flooded. I called them and they promised to come back to have a look. I tried to use it again and this time it flooded and tripped the electricity without finishing the wash and erroring. They came back and said they had no idea why it was leaking and I must try it again and let them know. They left. I discovered what I thought it was and have taken pictures of it leaking. Its coming from the under part of the dishwasher which they say is impossible. I have called them, sent text messages and they are ignoring my calls now. I can't touch the dishwasher without being shocked. Its now the 4th of October and I still have had no joy from them and I can't use my dishwasher.
