Sorry WWWombat, I read it slightly differently to how you wrote it.
Yes, the £26.49 as reported in the internal systems is the standard (old product) charge of £21.49 + the £5 you had previously set but what's important for most people is that, on changing products, it doesn't change to new standard charge + £5 it gets reset to 'no limit set'.
PN staff have previously confirmed that the 'data watch' figure reported on their internal systems is the total where the bit the customer sees and sets is the extra.

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.
