Topping up account - how much do I pay?

[Sandbo]

I previously started with a 90-day 6 GB data plan, with everything it cost $135 before tax.

Recently I realized I used data faster than I expected, and after 20 days since the registration, I decided it might be ok to go for 12 GB data.

While I tried the option of top-up, it seems the amount I will be paying become the new amount which is $205.

My question is, am I paying both the $135+$205 for this 90-day period,

or I will be charged only for the $205?

Thanks for the answer, it's good to know before I have done so. 

This way I might just wait it out.

@Sandbo  If you choose to change the plabn during your current 90 day plan, then you will be paying 135 +205, you will loose any prepaid value you had from your initial setup.

Your best option is to setup the change of account for your next renewal, that way you don't lose your value.
