Avast security not working after payment

On 12/28/18 you took out $54.11 for a paid subscription, this is the record in my checking account showing my payment…

RECURRING PAYMENT AUTHORIZED ON 12/28 DRI*AVAST SOFTWARE 855-745-3255 MN S308362639331562 CARD ****

Would someone please help me with getting my subscription working as I just got told that I HAVE NO PROTECTION as of today.
