There are other services like this available, like lucyphone.com which I wrote in this thread little while ago. This new site is called, GetHuman. I like that GetHuman displays the wait time for each number you plan to call.

Facebook is on the top of their list.. why the heck people are calling Facebook? As of right now, they have 572 minutes average wait time... for 10 hours of on hold time, you can get a lot of things done! Why wait? Seriously!

The site provides the wait time, customer rating, and also other means to contact the particular vendor.

I personally prefer using email as means of my communications. I don't like to be disturbed myself, and I treat people as I would like to be treated (nice, huh?). Now a days, some people are getting better results by using social network as the mean to receive better customer service! (here is an example) But some things will be easier to be handled by a phone calls, I admit. So when you have such need arise, use your time wisely by utilizing a service like GetHuman or lucyphone.com.
