We currently have cable modem service through Comcast. Recently the service has been fairly consistent, so my main annoyance has been the fact that they charge us $15/month extra for not subscribing to cable. So when I got a flier yesterday offering us "emergency" service for $4.95/month, this seemed (and was advertised as) a savings of $10/month. The only catch is that the promotional rate was only good through the end of the year.
So I thought I'd call them and find out how much it would go up. If it stayed under $15/month, I figured I was in good shape. After I called and asked about the promotion, the customer "service" representative asked me to fax her the flier because she was unfamiliar with the offer. I was flabbergasted. Wasn't there some sort of code on the offer that I could read off to her? No, she needed me to fax the flier. I probably could have done so, but on the principle of not encouraging their incompetence, I declined.
Now I remember why I don't have cable service from them.
