Customer service feedback LOL

I would LOOOOOOVE to give Cox -- or any cable company -- my (negative) feedback. But the ability to do that is not readily available. Hmmmmmm.

I received an email, that said, in part, "Find all ways to pay your bill at www.cox.com/residential/support/ways-to-pay-your-bill." with a link.

Clicked the link.....and.....

ERROR 403

Hmm...we can't find that page

OK. It asks provide some feedback to help us fix the issue.

https://www.cox.com/residential/flex-2/flex/pages/test/404.html#foreseesurvey

WRONG again.

ERROR 404

Hmm...we can't find that page

Looks like we had a few wrong turns. Let's get you back on track. But first, provide some feedback to help us fix the issue.

This is the circular Catch 22 ** from cable companies that drives me crazy. Not sure who is worse, Cox or Comcast.
