Keurig K150 and Brand New K70 Machines don't function as they should. waterbury CT

I have a Keurig K150 Commercial Coffee maker that never worked as it should from day one closing the coffee k-cup pod holder on the machine. The company new that it had an issue with it but kept giving excuses. Well today, my K-cup pod holder stop working, remember, always had problems with it closing correctly. Once closed, the machine doesn't seem to recognizes the K-cup door being closed to start brewing. I had purchased a backup machine which was still in the box stored in my closet, the model of it is K-70, so I pulled it out and plugged it in to use it, and it's not working correctly, giving a Not Ready Add Water Error. I called and spoke to Keurig customer service and the Keurig Commercial customer service about the issues, all they try to do is sell me another one of there crappy machines. If you get on most of the Classified ad sites, you will notice how many people are trying to get rid of these coffee makers, they are nothing but problems waiting to happen. They are not built with quailty. Just a waste of money! My opinion, don't waste your money!
