As others have noted, it is near impossible to get this company to stop charging your credit card once you are, like I was, silly enough to respond to one of their "free" offers. I have written to them telling them to cease and desist but to no avail. Next, I intend to advise my credit card company that they have used my card number fraudulently and ask them to treat it as a theft. I will also be writing to the USA Government Scams and Frauds section and asking them to investigate the company. Their website is https://www.usa.gov/complaints. I would encourage others that have been stung by this crowd to also contact them.
I would not recommend them to an enemy, let alone a friend.
Bottom Line: No, I would not recommend this to a friend
