I was able to resolve several issues with Metrocast by contacting the parent compay.
They are a little tricky to find... If you type in
www.metrocast.net... you just get the local office..
Type in
www.metrocast.com... and you get the parent.. Harron Communications, in PA
They have a list of the corporate officers... and a contact us link. A few polite but firm messages to that line got me a call back and a quick resolution to Billing and Service issues..
Hope this helps
