busy tones

I get very annoyed when people dont answer there phone! I mean I know people have lives outside of me and I don't expect them to jump when I call (but I defiently wouldn't mind if you did). But when you are trying to get a hold of someone and there phone is busy...that is a different story! I have been trying to call the health clinic all morning, to get my results, and it has been busy! I mean come on its the 21st century! Heard of call waiting, or an answering machine! You have a hundred different contact numbers and every single one is busy for the last 3 hours! It ridiculous! Thats all I had to complain about today!!!
