Purchase 3 years subscription instead of 2 years

Vania, Have a look @ this AVG webpage (https://support.avg.com/support_sales_chat?l=en).

I make a mistake in the order window.
I want to buy 2 year subscription AVG Internet Security Unlimited.
Any chance I can change my order from 3 to 2 year?

Thanks,
