This is exactly the cause. The ATM overhead is being counted by AT&T and it has been a problem ever since they started metered billing.
Now they *shouldn't* be doing so because that is a bit like the water utility charging you for 11000 gallons when you only used 10000 to account for leaks in their system or the gas station saying you pumped 1.2 gallons for every actual gallon to cover the fuel used to bring the gas to the station, but until they are regulated like a utility and the appropriate regulator steps in there is just about jack you can do.
