Honestly, the best way to handle these things is to forget even bothering with the company and file a charge-back with your bank or Visa/Mastercard. You have every right to call up your bank and deny a charge for a service you're not using, and didn't ask to renew.
Plus it's guaranteed to get the charge removed immediately, and you'll be hurting the company by adding to their charge-back tally, increasing payment processing costs for them and potentially completely cutting them off.
