I must say is less more when I look at your question...your emailed statement advises period costs, from when you joined as in day 1 date. Your statement is dated on the same date next month (period 1), and its emailed the day after attached to your email as a PDF doc.
The APP is updated accordingly for each period.
Your DD's as you know are explained in your welcome pack and are not affected by your statement until review time x 2 a year, unless you prompt for the same and approach PP via wattBot, to get a team members response, as the method is regularly advised on this platform.
Is there anything else you need just revert back lots of member customer ready to chip in offering solutions to many things.
