If you have donate and received confirmation of the cash transfer, its usualy very fast but you know, Lillu has a life too, especially in that period, he might have been a little busy.
I doubt it has been days if you did it correctly for I have donated or had donations made in my name well over a 100 times and never see it take more then 6-8 hrs and normally is around 1-2 if Lillu is on forums
