I still have a problem with your installers saying they installed my dishwasher when they didn't. Came into the store where I had purchased the appliances, the employee told me there's nothing they can do for me. I told him that I did all I could do. Came to the and told them that they did not install the dishwasher, that the Plumber we hired installed it the next day, because he had to hook up the sink anyways. I was told tgat after the first time I came into the store, that someone would call me the next day, never got a call from anyone. I even told them that I have the receipt from the Plumber. He said well I instant that. I went to the store again on the *******, and explained to them again, still with no results. Called and asked to speck to a manager, she said she would email someone, and they'd get back to me within **hrs. Haven't heard from anyone. Just want a refund for the install that was never done by your installers.
