Ksv1870 report processing time?

Hi! I just applied for a student residence permit extension and ma 35 asked to send the confirmation of no loans in Austria. I understamd that they only accept ksv1870 (or are there alternatives?). I applied for the free one and it says that it takes 10 days in average and there is a paid one ready in 3 days. If anyone ordered this report recently, how long did it take to receive the free vs paid one? I have to travel soon and trying to decide what would be better to do?
