Bad service non existing repairs

My dishwasher broke two and a half weeks ago, they replaced some parts but it still did not work. They came to take it away after many phone calls and empty promises. When it eventually came back it still did not work. After more phone calls and empty promises they refused to give a refund. I had paid in full and was promised that they would pick up the machine again and a temporary replacement would be given to assist over the xmas period which never took place, my calls have been avoided by both the managers and the technician who has been dealing with my machine.<br> <br> Everyone keeps passing the buck and the office is useless. I keep getting passed onto different people and never get a call back and if I do it's all lies. I have requested a refund however, they refuse to give me one, but also can't seem to fix my machine. <br> <br> I find this to be totally unacceptable as I am stuck with a broken machine that has been paid for. I do not want to deal with them anymore and just want my money back.
