What exactly am I going to do?
Stop pissing into the wind maybe. If it was as big a problem as you let on then they will fix it because people get mad and spend money somewhere else, fix it on their own at their own convenience or not fix it at all. You can say whatever you want but Steam has consistently improved over the years so chances are the minor issues will get fixed over time because infrastructure problems take time to fix. That's what they are by the way, minor issues. The service is up and responsive, people are playing their games, buying games and all that crap.
