Customer Reviews of Internet Providers in Charleston


I've been a Comcast customer for years with the only other choice being AT&T. The speed is fine but the price is way too high and customer service is the worst of any business I've ever done business with. Problems I have are always due to something within Comcast. Recently they added a primary email address to my wife's account without even letting us know, then they began capturing our home phone voice mails. We didn't know this until someone told us they left us a voice mail. When calling Comcast I was on the phone for nearly two hours with someone I could barely understand. I couldn't access our voice mails then they deleted the eleven emails we hadn't heard. They suck!
