reimage Software-UC.com/software Saint-Laurent QC Unsolicited contact with no help and charges to my credit card Saint-Laurent, QC Internet

I had been experiencing some intermittent "blue screen" issues with my computer for a couple of weeks when a popup showed up one day from "reimage" offering to run a scan to fix problems with my computer and make it run faster and more efficiently.  I was immediately given a phone number to call and the tech told me he would have to take over my computer, which I did not allow, he told me that there were many problems with my computer and he recommended that I take it to OfficeMax or Stapples to have a "professional" fix it and told me what he thought that would cost but offered to have "reimage" fix it immediately for about half the price starting at around $300 but finally dropping it to just over $100, I refused.  I was started watching my credit card statement online and the next day found a charge for $41.95 on my statement and I received an invoice from "reimage" via email.  Within a couple of days I read an article in the AARP Newspaper about scams like this using almost the same script that "reimage" had used with me.  I have challenged the charge with my credit card company but they have now put the charge back on my account.  I read the one report here about this company and have found multiple articles, and complaints about this company and this scam.
