I vote for useless.  Although you could make the argument it is non-existant given the fact that some can hardly speak English, the reps lie, they don't call back, they often don't answer simple requests like a tracking number, and finally, what they do say is just about worthless.

 

My suggestion.  HIre the Cub Scouts to run Customer Service--at least they would try to do a good job, and they would be honest.
