Sometimes a customer support will expect you to do all of your own work alone but this DreamHost review shows why DreamHost support is one of the best. The first thing is that rather than tell you to fix your own problems, the support will do it for you because they can access your account from their remote servers.
If you are having problems with errors popping up left, right and center, you will be able to contact the customer support any time of the day or night and they will be happy to help you. It may be the case that you are passed onto someone who is more suitable for your particular situation but you will not find yourself on hold for hours.
One thing that the customer support is not able to help you with is anything that you install yourself, such as PHP coding. If you are having a problem with this, you will have to find the solution to it yourself. This is stated up front, so you are not suddenly told.
