Extension of avg product

i accidentally unsubscribed my avg product while trying to input an extension activation code for my avg-ultimate. how do i undo what i have done and be granted my subscription again.

i was awarded 3 months extension for my avg-ultimate due to pricing difference discovered between avg and third party sales agents. could a sales rep or tech staff help me with this. 

Hello Jess,
It seems the 3 months extension has been applied to your existing subscription. You have AVG Ultimate valid until 2019.9.10.
I can see that you had contacted our chat support team regarding this. You can contact us again if you need any further assistance.
Regards,
Alok.
