Query: bad service, no warranty

Bought this unit along with 2 patio stations and 7 room stations when I was doing the rough wiring building a new house. A year later now house is completed (hey it takes a while to build a new house). I try to use the intercom and one station does not work. I am told by manufacturer and people I bought it from 'Sorry your warranty is up, too bad'. And they expect me to buy a new one, they don't even service them. I would not buy this or any other product from this company.
