Safecart SpeedyPC criminal scam Vancouver, British Columbia

My PC was running slowly, so I went on Google to find a free fix. I clicked on an ad for SpeedyPC, as it advertised itself as a free download. I opened the application and it performed a scan, notifying me that there were 900+ errors on my hard drive. I clicked on the "fix problems" button and it said it had to be registered first. I filled in the registration info fields and clicked the button. Another dialogue box came on and said I had to pay to get the full functioning version. There was a price of 29.97 with a slash through the price, saying it was on sale for 9.97. I thought this was a good deal, so I entered my CC information. I pressed the "buy!" button and received an e-mail receipt that showed that I had been charged 29.97 + 9.97 for some other program I did not order or even see on the website (the program is called "Privacy Controls"). Within 5 minutes, I received a phone call from my Visa/debit card issuer's (Golden 1 CU) fraud detection division, asking if I had made the charges. They explained that they had received an alert due to prior problems/complaints with the seller. I explained that the charges were fradulent. They told me that since I had authorized the transaction, all I could do was call the seller and demand a refund. They gave me a phone number, which I immediately called, and got a recording that the phone number was out of service. I got another phone number from a complaint website suppossedly for SafeCart's customer service (877-320-9229). This number gives nothing but a busy signal all the time. I guess I should have done my "homework" first before buying what appeared to be a good deal.
