Hotpoint Ariston Dishwasher Faces Frequent Breakdowns With Subpar Customer Support

My Ariston dishwasher stopped working on October 18th. I reached out to Customer Service on October 19th. The technicians discovered that there was a problem with the motor, which was causing the machine to overheat. As a result, they decided to take the machine in for repairs. They told me it would be back in a week, but it actually took 10 days, and the problem is still there. It was picked up again and returned after a week, but the problem is still there. I reached out to customer service to talk to someone who has the authority, but they said they would get back to me, which hasn't happened yet. Today, the machine made the same mistake again while their technicians were there. I don't want my device to be taken away anymore. I want my money back. Can I find someone to chat with? I've been in a really tough situation for three weeks. I don't want to take legal action; please give me a refund of my money.
