If you saw it and was concerned enough to take a picture why the hell didn't you question them before they finished the ceiling and boxed in the pipe work. It would have saved you a lot of stress.
There was a bit of a language issue, and it was plastered over before I got the chance to express any concern to someone who would understand me. And I'm not the client, Camden is the client and I'm just a lowly tenant who'll get called a trouble maker if he speaks out of turn.
