I changed my Mobile Share Plan from 4Gb to 1Gb. On the date of change I was charged for both 4Gb plan and 1Gb plan. How can one use both the plans on the same day is beyond me. I know it is only a few dollars (for 2 lines) but this is exactly the kind of situation that brings such disrepute to AT&T and I do not know why AT&T indulges in such practices.
Any ideas anyone?
