Question about Line Rental Saver

[#1]

We are currently on the basic broadband package with prepaid Line Rental Saver. I am being tempted by your fibre broadband offers. What would happen to our Line Rental Saver, if we chose to upgrade? Thank you.

It's like when you buy a 2nd class stamp so it would seem, always valid even if price to buy goes up.

It mean's that you lose money.
