Sitting on hold for half the day

I have been sitting on hold for over half an hour waiting to get through to someone in the sales department. All I want to do is find out the status of my contact application. When I previously called 2 days ago, I sat on hold for 45 minutes only to be hung up on once someone finally picked up.If you have waiting times of that long you should invest in some extra staff! It's appalling waiting that long! I'm now considering paying more for different companies because they don't make me wait that long! Ridiculous!
