Unable to cancel subscription

I received an email announcing that my subscription would be renewed next month.  I wish to cancel this subscription but am unable to do so.  None of the instructions given in the message works.  I cannot even display my subscription.  I would appreciate your canceling this subscription at the end of my current subscription period.  Thank you.

Hello Christian,

I can understand your concern. Please do not worry, I have cancelled the automatic renewal for you from our end and you will not be charged by AVG automatically.
