I think your bills should be paid within 2 weeks! that's the esssence of the eräpäivää. But you don't seem to respect the time frame when it's you who should refund. I need you to listen. I'm only going to say this once. I have a very special set of skills and you need to refund my cash with interest immediately!
You(Sonera whoever it may be) can ask me for more personal infor if need be.
