They probably misread your old meter when they removed it (or wrote down the reading for some other meter).  Happens all the time.  Look at your bill -- there will be two readings, one from the old meter and one from the new one.  Calculate the kWh per day for each one.  If they are drastically different, call up customer service and complain.  Demand that they re-read the old meter -- they have them stored in a warehouse for a while.  They will fix it eventually, but it will require some persistence.

Another possibility is that they haven't read your analog meter in a while and you were getting charged estimated readings.  In that case, the bill may well be correct.  It's also possible that the old meter was under-reporting electricity usage.  

1. Check your last bill and write down the current meter reading and date.
2. Read your meter on the same day of your current month.
3. Subtract the reading on the bill from the current month and see if it agrees (within a few kwh).

If it does, there is not a lot you can do.

If there's a large discrepancy, ie: you show 1000kwh and you're billed for much more, have the electric company check to see if your meter is actually the one billing to your account.  Mistakes are occasionally made. It should have a serial number and an identifier sent to their computer.

I wish you luck in this.
