we moved into a rented property two months ago and since we moved in the shower has been broken. It does not drain, meaning that if we want to shower we have to scoop out stagnant water or smell indefinitely. With three people in the house, the situation is quite severe. We have notified the estate agents (we do not have contact with the landlord) but they seem to now be avoiding our calls after about a month of empty promises (we called them with our caller ID withheld after weeks of futile unanswered calls and they picked up immediately). How should we go about this? Would it be possible to withhold our rent until it is fixed? Many thanks!
