Heal -n- Soothe Health Back institute automatically sent me more product without permission and charged me for it. Austin Texas

I ordered Heal N Soothe to test it out and found it doesn't do a thing for me so I call to cancel my order and I am put on hold for a bit and then I get hung up on so I try again and the same thing happens it says they will transfer me to a customer service associate, I am put on hold again and again after about 20 minutes I get hung up on so I try two days later early on Monday morning about 10:00 and again the same thing happens.

I want to cancel there product coming to me and getting charged for it but I can't even get them on the phone so they charge me $50 plus dollars for something I don't want . There company is setup to steal ones money . How can I stop this from happening to me ? I am going to go to my bank and see if they can help me by maybe putting a block on charges being made on my account for this company.
