Upcoming subscription renewal fee

I received an e-mail stating that my subscription expires on January 25, 2020. And that I will owe $139.99.  Yet it says my original order was August 14, 2019 which is only 5 months worth of subscription.  Why will I owe this much so quickly.  My original order # is 65395518900 if this is helpful in looking up.

Hi Carla. 
We're glad to clarify this. 
Recently, AVG is partnered with the established eCommerce provider Digital River, which manages the online sale and distribution of AVG products and services.
A new order (duplicate) was created with them regarding your purchase during this transition. 

The original order date of your 2 years subscription was in Jan 2018.
