i'd want to know wat we call "a person who never keeps his promises".. i tried searching it out over the net, but couldn't find it anywhere..!
You can call that person a promise breaker. Actually you can find some references to promise-breaker on the net, but I don't think that the one-word hyphenated form is widely accepted.
You can call such a person unreliable, but of course the meaning is not a specific as promise breaker is.
