I pay almost $1000.00 to have a disposer install on my sink when I asked for a itemized list of charges I was told he couldn't do that. I asked how much the machine costed he didn't know that. I called the company today and asked for an itemize list of charges and they sent the same invoice I received the day before I will not do business with them again they charge way to much and won't tell you why. I wouldn't have got as upset if they just broke down to me
