Where do I order part for Haier Portable Dishwa

Question

Hi my son bought an Haier HDT19PA table top dishwasher fron a friend but he does not have the buy date and there is no warrently on it anymore. He needs a quick connect adapter before he can run it. How much would that cost and can you mail it me??? I want you to know that I have tried to call and email and I called your warrenty number on 11-27-08 and they said they do not handle getting parts, but also did not give me a number I could call. You know if you can't provide parts in an effective way. I have decided that I will never buy a Haier appliance ever again. If you can't get customers parts then I do not want to be your customer.
