how does upgrading my account from bronze to silver affect my payment plan ?

We have just paid for another 2 years on the bronze package but now need to upgrade to silver. How does this work, will we just be billed for the difference in price? or do we have to pay for the whole silver package in addition?

When you upgrade your plan, your unused time from your current plan(Bronze) would be credited to your upgraded plan Silver.

Hope this information helps.
