Three companies, three problems, one day! I'm on a roll!
With this company, my online account was having problems. The customer rep I called said they knew about the problem and that it only affected certain accounts, but their systems were down so she couldn't transfer me to the person who could fix the problem. Her advice was to "wait another billing cycle and see if the problem's still there."
Their system was also down the last time I called, a month ago. Either they have a terrible system, or it's a convenient excuse to avoid doing anything.
If I ever start a company, "customer service" isn't going to be a PR phrase, it's going to be a top priority.
