Some of you may be aware that I sometimes describe my job as "professional complainer". This is definitely an example of how the 2P approach (to coin a phrase) to dispute resolution can pay dividends. When trying to get an issue resolved, the key things to bear in mind are (1) be polite, (2) be persistent. The latter will get you past the stage in the complaint handler's procedure where they are just trying to encourage you to go away so you are no longer their problem, the former will make them care enough to want to solve your problem.
Sorry to those of you who are bored with my current Dragon Age obsession. At least I'm posting a bit for once, eh?
