First of all are you absolutely sure that e.on were/are the supplier (lets assume so)
I suspect that the message from e.on is a stock message, as though you were switching because effectively you are switching to them even though you're with them. (I know that sounds odd)
There are 2 possibilities here, I think the application to switch will make it's way to e.on, but I would contact them in a few days to check if they've had it. (leave it a short while so it can get through their systems) Once they have the application they will either block it because they will want you to settle the bill or allow it. What definitely won't happen is that you will switch to PP and back again.
It's all down to the timing at e.on's end and how they reconcile your address data.
Worst case is that it may be a better option for you to cancel the switch (you have 14 days), sort e.on out and re-apply, but don't do that yet.
Strange when I quote your message the bit in the middle disappears!
