Royalty Check

The check stub on my first Royalty check is not correct. I have called and emailed PennVa. several times and have just been told that their bookkeeping dept. is short staffed. The calculations that I checked randomly are not correct and the gross sales are different on mine and my sibling's check. I know our division rates should be different but the gross sales for the same time period should be the same for all royalty holders and oil lessee in my opinion. If they should be different, please someone explain or let me know if you have had the same problems.

Still have not heard anything !!!
