Claims department run around

My baby room (yes I am 6 months pregnant) has been under water for 3 MONTHS! They have sent out 5 different people to assess the problem. 4 of them saying the water leaks from outside when it rains and that they can’t find the problem. Every time with an excuse until my husband hit a giant hole in the wall to find the leak himself and called them again. So on Monday they sent plumber number 5 that found the problem within a few monutes and then cut off my water. It is now Thursday and nothing has happened. They have sent no one to fox the problem. Called their call centre 3 times today already not to count the previous calls. No one can help me. Each person blames another for the wait and still my water is off and the baby room is still wet. They keep saying they are waiting for paperwork from one of their own departments as the plumber sent his report days ago. Spoken to several people just passing me one to the next blaming a different department and not helping me at all. For three months this has been going on. Each week my husband phones to check on the progress and each week nothing happens. Laminated flooring has been thrown out, our second room has now also been damaged of the water leaking through the house from the baby room. My anxiety levels are rising and I fear the room will not be ready if baby comes early.
