Valence Operating - Harrison, TX

My aunt is having some challenges with royalty payments from Valence since they switched to an ACH platform. All steps taken to comply with the direct receipt of funds rather than the old school check have been completed correctly. However, though my aunt’s sister who shares an identical interest is receiving her production funds monthly since the switch, my aunt has not received any since the change. This is now been going on for four months.

Multiple calls, emails with complete documentation & owner number screen shots, etc. have garnered no response from Valence OWNER RELATIONS. I’d like to as you all, where does she go next to get this resolved?
