Had to learn the "California Job case" in shop class around 1982.
We just had a big fight with our local paper that resulted in the cancellation of our subscription.
We used to enjoy relaxing and reading the paper with our coffee on Sunday mornings.
They use an out of state billing service that doesn't report payments in a timely manner, and that caused repeated calls informing us that our account was past due, even though it was actually paid ahead 2 billing cycles.
No one on the other end of the phone had authority to, or knew how to contact the out of state billing co, even after we became aware that this was the crux of the issue. Each time this occurred (about 5 times in 2-3 years), it would take up to three weeks and three to four phone calls to resolve, and after every call in which we were told everything was resolved, the very next day without fail- another "collection" call would occur.
Additionally, we averaged about one missing Sunday paper every six weeks, and whenever we called to report it, we were told "there's nothing we can do because your account is past due".
Then there was the ever increasing "minimum subscription". First it was Sunday only. Then you had to get Saturday and Sunday, then Friday, Saturday, and Sunday, and finally Thursday, Friday, Saturday, and Sunday- WTF?
You would think for an industry that's losing business hand over fist, that just a bit of effort and maybe a little logical thinking might go a long way towards keeping subscribers that actually WANT to patronize your business, instead of throwing up hands.
