Gerryv23, our goal is to make sure your bill is easy to understand, we're here to help. When you compare the taxes and surcharges from the previous month are those numbers the same?
One way to see would be to compare this month's and last month's bills. What has changed? My guess would be the taxes/fees which can change occasionally.
For example, My bill in January was $203.20, my bills Feb thru Apr was $203 and my bill this month is $202.80. The only thing which changed were the taxes/fees.
