Don't ask for a refund, go to your bank or CC company and charge back the 6 months. That'll hit them where it hurts. Little known fact about chargebacks: the merchant pays an administration fee, typically $20 to $50. Per charge! That is why the smarter scammers refund to everybody who complains, not refunding is plain dumb. This scam has been around for a long time, usually it's adult companies that sell you a 'free'…
If the company continues to receive chargebacks claiming fraudulent charges (which this really does appear to be) they will find themselves in a difficult place with card processors.
Some processors drop clients if they crack 0.5% a chargeback rate.
