Experiencing Service Issues With Exede Internet

So I currently have the Liberty plan and even when I have all of my data available this service is horrible. You all promote lighting fast speeds and this and that and it is nothing, but crap! Believe me when I get the first opportunity that another service is offered I will gladly pay my months of my plan that I will have to pay to get out to go to either Time Warner or AT&T. I have also called a tech that provides service calls and they never showed as well. When I call in as well takes forever and a day to get someone on the line. So thanks for the crap service!
