Cancellation of all subscriptions

Last year I cancelled all my AVG subscriptions and cancelled the credit card authority.  This was totally ignored and I continued to have my subscriptions renew despite cancelling my credit card.  I once again went into my account and cancelled all AVG products and requested a refund where appropriate.  Today I have received yet another renewal through Digital River Ireland.  I no longer have a computer and haven’t used AVG products for more than 2 years.  In fact I have even had reminders that haven’t used certain products and providing an activation code.  What do I have to do to stop these now illegal unauthorised charges and order AVG/Digital River Ireland to finally accede to my cancellation???
