51 Talk review: Bogus charges and no response to my emails 1

I was furious when I found out that the company 51 Talk charged me for $100 and no one informed me about it. I used their services, but I cancelled it several weeks ago. They didn’t charge me, but recently they started again. I want to stop it, but I don’t know how, because they don’t reply to my emails. Maybe someone has any idea how to contact this company and return money back, please contact me then or leave a comment. Thanks.
