Xfinity ranked worst company in US

In my personal list, Xfinity is the worst company in the US. Why do people still work there? Aren’t they embarrassed?

Xfinity makes money by taking advantage of its local monopolies to charge customers for services they don’t provide (charge me for 1.2G connection, but actually provide 6Mbps). And they make it impossible to reach customer service so they don’t have to address the issue and provide the service. Customers like myself are stuck with 6Mbps because we don’t have a choice.
