I appear to have lost all my points, all 7,000 or so of them. I just presumed my DB credit card would renew automatically and I thought I had paid it, but obviously not. So the points just disappeared, without even mention of a Storno on my account. There's no sign that they actually existed. Obviously it's too late now, and I should have looked at my account more often (shows how inspiring bahnbonus is). But I just forgot about it, possibly because my main residence is now in Switzerland.
Realistically, I expect that nothing can be done, the points are gone. Can anything be done, do you think? Maybe even Kulanz Punkte? I personally think it is a bit harsh, just to evaporate all my points like that, with no warning at all (I received no Hinweis whatsoever). At least with the airlines you get a bit of time to spend them...and usually some sort of warning. I suppose Deutsche Bahn is a monopoly, despite the rise of other operators, and just doesn't care. I also think the value of the points has just gone down and down, given that I can often get such cheap Sparpreis tickets all over the place.
