Belvoir - Dundee

I have been trying to contact them this week regarding water leaking from our bath and causing water damage to the carpet in the hallway. I have raised it twice through fix flo, phoned multiple times (no answer) and left 3 voicemails. This is ridiculous considering our other shower is out of action due to the same problem (except water leaking though into our kitchen ceiling) I have been renting this flat for over 6 years and kept the flat in excellent condition. I have also been more than understanding through ongoing issues with the bathroom over 4 years. Total disrespect on their end. I will take this higher if I have to
