Acentive Scam Artists Internet

They scamed me out of almost $300 that I can't afford. I signed up for help to clean up my computer. I was told that someone would call me in 4 hours. # days later while at work they call me. I told them to call me that evening whe I was with my computer and I never heard again..that was 6 weeks ago. They charged my Credit card and when I called to get the charges removed they said it was past the 7 day refund policy date....A refund would imply you gave me something...you did not!!!! Ready to take thisd to the media!!!
