Renewed the subscription but start date is not back-to-back?

To AVG support…

I received an email  to renew my AVG 2 year subscription that ends in March. However I clicked the link in the email and paid to renew but the new subscription ends a month sooner. The subscription should start when the existing one ends in March.

Kindly adjust it thank you.
