Xfinity (Comcast) support is non-existent and actively lies to me about promotions or what I will be billed. Every time I call them to dispute, they waste an hour of my time and either throw me a $10 credit that I'm not sure is even getting applied. Different departments don't know about what the other is doing.
I'm now getting charged $70 for international calls I did not make.
How can I escalate these issues? Can I just cancel all association with them cleanly by reporting them to my credit card company? They seem ok with atrocious service because of their monopoly. Why do we put up with this blight?
