I received this postcard, too. I had DVR 25 and DVR 26 as credit on my August and September bills, but the credit is gone from my October bill. Anyone else lose it or is this an individual billing mistake?
Same here and the autopay for 9-13 was $7 and some change (probably tax?) lower than it should have been resulting in an outstanding balance added to the 10-13 bill. Will be contacting DIRT.
