They continue charging after cancellation

I subscribed to their service on their website. A week later I canceled the membership because I didn't find it worth the money they charge. However, a month later I've noticed a deduction on my credit card statement of $14.95. The transaction was made by ATHOMEREWASRDS.

I wrote them several emails, and called them. They ignore my emails and hung up on me when I called.   Last month they charged me again. I am asked my bank to block all transaction requests from this company. Has anyone else experienced this with this company?
