On October 26/16 I went online and changed my plan to the $25.00 Plan. It said I had a tab of -$16.27. On my next bill I was charged $35.00 instead of the $25.00. Also on Nov. and Dec. bills I was charged for the $35.00 plan instead of the $25.00. Today I see it is $28.00 instead of $25 for the lowest plan, which I have changed to. I would like the plan I signed up for in Oct./16, and credit for the over charge the last few months! Thank You.
