I have the exact same experience as a previous poster.
Back in May 2012, I received an advertising for a $9.95 language course, guaranteed to help you learn in 10 days. I decided to order it for my husband who was travelling and expressed interest in learning another language.
I'm very careful to look over everything before I order as to not receive newsletters, etc to fill up my mailbox with spam. I was re-directed several times before I got to the advertisement on Stroll. Then again directed several times. I almost didn't order because of all the confusion. I paid for the course, but didn't trust them, so immediately called and cancelled.
They STILL charged my credit card but I did not receive the merchandise.
In July, 2012 I received an email from Stroll Customer Care Team that there was a problem with my credit card and that they were trying to debit it for $256.00!!! I responded back asking why they are sending me this. I stated that I had not ordered anything from them.
Again, they sent me a letter. I asked them to stop contacting me and that I did not order this product, but the man on the phone said that I did order it and my account will remain in their collections. I continued to try and explain that I do not have any other orders with them. In 11/2012 I received a collections letter, including my email address, but still, no email.
So I called them again stating that I had not ordered any product but the man on the phone continued cutting me off and kept saying that I had enrolled in their Special Language Acceleration Program! They also stated that the "package" that I received was a 30 day trial, which I am VERY careful to read thoroughly and avoid offers like that. Then to make matters worse, they said that they would not authorize a return request or provide a per-paid shipping label after the trial ends and demanded payment!
