Royal Biz www.royalbiz.info Steals my money. I cancelled my subscription, but still pay. Internet

I am so upset that I signed up for this. I immediately regretted my choice to share my credit card information, but I was unable to successfully cancel.
I called the number on the website and to cancel months ago. The man on the phone sounded American and told me there was no problem. I would only be charged 1.99 once and the 59.99 would never be charged. Some months later I received a peculiar email alerting me that I will be charged 59.99. I called immediately and left a voicemail. And emailed. I knew for sure this was a scam now. I am angry at myself, but this is not my fault. I should not be punished by these criminals.
The next day I received a phone call saying that no money would be charged. I was caught off guard and just said "Ok, thanks" Later I questioned how they got my phone number and become more angry at myself because I must have given them my phone number too.
The company has my full name, my email address, my credit card info, and my cell phone number. They have access to all sorts of things and their possibilities are endless.
I feel awful and hope I can gain some support from this network and discover a way to stop this company from having access to me and my money.
This is the hardest lesson I have ever had to learn and I truly hope this company is not allowed to continue to con people.
