Any advance broadband charges prior to activation, would normally be credited on your next bill. If this does not happen, then please post back here.

I believe the dates you see are in the "What You Used" section underneath "My Bills". It will show the 25th of March, as that's the date you will have placed the order, up until the day before your service went live/day before your next billing period. There are no charges for this period. This section will come in useful for future bills but we implement it from the beginning.
When you view the bill itself, or download to PDF, you will notice that it states "The following advance charge for your package includes your line and applies from 10 Apr 2017 to 9 May 2017".
