She's a student, moved into a new shared flat in September. They had problems at the beginning with various fixtures and fittings - showers, heaters etc, but they seemed to get sorted eventually.
But now the central heating isn't working, hasn't been since before Christmas. DD has phoned the letting agency numerous times and is always told they will send someone round. The girls are running the tumble dryer to try and keep the flat warm. Also, the bulb in DD's bathroom blows every time she replaces it. Obviously there is something wrong with the electrics. Nothing done about that either. There's no natural light in the room so she can't use it.
What should she do now as her next steps, and if it isn't fixed, can she get out of the contract? She's had enough.
