Books-A-Million review: charge on my account

While I lived in Monroe LA, I joined Books-a-Million. I was there only for six months. When I moved to Georgia at the end of 2017, I notified them that I would no longer be a member; however, they charged my bank account for 2018, but I let it go thinking I would go ahead and use them online. I did notify them again that I no longer wanted to be a member. They have charged me again this year and I'm getting the run-around because I want a refund. I've notified my bank to stop any further charges.
