we have a toilet block on a site on long term hire. it keeps flooding and blocking with the associated effects EFFLUENT flooding across the drive. we informed hss on Tuesday email, it is now Thursday and still we have no attendance from hss to put it right. I have phoned our customer manager no answer (twice) no return call, I have called customer services 3 times been cut off twice and third time informed that our customer manager had dealt with it. But the toilet block is still leaking!!!!!!!! They are such a poor company one star is too high a ranking for them!!!!!!!
