It depends, you wrote this:
smaller than 1000 EUR will get in a priority queue and used to fill the daily quota
larger than 1000 EUR, up to 30000 EUR are processed in FIFO order
Do you count exactly 1000 as above or smaller as 1000 row?
And from which date do you count the 10 business days? From the day you received it? On of my orders was around 93 but still didn't get through eventough 10 business days had passed since receiving the first order.
I don't know if the limit is <= 1000 or < 1000. The 10 business days are counted from the date your last payment was completed. Unfortunately cancelling seems to count as completed as well. 10 days is variable. It depends on the current queue, and used to be higher.
