After moving, I received my final gas bill for $36.11 on 21st September with a due date of October 11th. THe read type was "actual". I then received a bill on October 11th for $24.54 with a due date of October 30th and a read type of "estimate". Both bills were for the same time period. The website and app both state the amount owing is $40.98 with a due date of September 20th, though this amount was paid on September 15th. Anyone care to take a guess as to what I owe and when it is due by?
