Depends on how bad this is gonna turn out time & money wise. It might not be worth my time/effort/stamps, envelopes, printer ink & paper. Plus they will say that they are aware of the problems and are in the process of fixing them (ie. roadworks absolutely everywhere for the last year with not a single worker seen there. ever. There are a load of stupid rules along the lines of "we inspected it within the last 6 weeks. therefore it is not negligence". Hopefully this will be a straight-forward repair.
