I have ran my own medical practice for almost 10 years now in the Detroit area and during that time I had numerous problems with AT&T. The DSL always slowed down and getting through to customer service was almost unbearable.
I switched over to Cbeyond last year and I have no complaints at all. In fact I have been more than pleased by the level of service and the professionalism of the sales rep that sold to me. Everything they said they delivered on and I couldn't ask for anything more.
I happened to come across this site and was surprised by the comments being made. Perhaps those consumers who are so outraged should spend a little time researching their competitors.
