Hi, Jonathan.
We'll definitely help you with this. Did you try to click on 'Renew now' in AVG PC TuneUp application if it is installed on your PC? If that did not help too, we'd request to contact our sales team (https://support.avg.com/support_sales) for further assistance.
I want to renew my license for avg tune up, yet at payment section, after I write out my credit card number and all, it said "Payment Authorisation Failed", I have tried it on another browser, another pc, even using my phone, yet it's still said "Payment Authorisation Failed".
Months before the payment was accepted with no problem, until recently it was always failing, I have asked my credit card bank, they said their service is still working without problem.
