This is the problem. You been bumped will have been caused by some other customer ringing up and kicking up a fuss, so customer services solve their issue to your detriment.

Then you ring up and kick up a fuss and your problem is solved to someone else's detriment and then they ring up (well I'm sure you can work out the rest) until someone finally doesn't notice and they gets the bad news at the airport.

Just keep monitoring your flights.
