Avg Internet security - Not getting what i paid for

So I signed up for AVG Internet Security for a year as I had performance issues that needed to be resolved. Going from the link I bought it and activated it and yes it's great but when I come to resolve the performance issues it's asking me to pay again… is this service not available on the plan I bought?

Greetings, 

We will clarify this for you.
Performance Issues scan is an advert for the AVG TuneUp, if you check the page where it ask for payment, AVG TuneUp will be mentioned. 
If you wish to purchase AVG TuneUp, contact our sales team this 'link (https://support.avg.com/support_sales?l=en)' if not you can ignore it.
