Talk to your credit card. I once did that A+ Certification training course videos from CompTIA. It was try one for 30 days and if you don't return it they send you the rest for $500. Well I got the first DVD, watched maybe 10 minutes of it and determined it was pathetic and for the adults with a low IQ. I returned it the next day after having called them and received a confirmation.
Well at the end of the month I come home and BLAM there is a HUGE box on my doorstep. I open it and its the whole series and a receipt/billing slip showing a charge for $500.00. I contacted them multiple times and they gave me the run around saying they never received it etc etc can't return them, they are pressed to order they don't keep inventory blah blah.
Contacted Citi-Cards, told them what happened. They removed the charge, closed the card, expedited a new card, contacted CompTIA. Within two days, I had a guy who was scared and stuttering like crazy on the phone apologizing and sent me a BOX prepaid to take the stuff back!
Credit Card's are sometimes a good thing!
