Terrible call centre "music"

At this stage I cannot comment on poor service because my problem has still not been sorted out and I am getting chased from one person/department to another. But my complaint is about the terrible distorted looped noise (not music by any means) that I have had to listen to over the last 3 days while waiting for call centres to respond. PLEASE put some music - even the sound of dripping water would be less torturous.
