Charged Twice

This company is [***] horrible. Excuse my language, but I'am really upset with this company. I was charged twice. & I called them and they denied it. When in my credit card statement says I've been charged twice. The first customer representative was really rude. She kept denying everything and told me to hang up. I talked to her supervisor. She kept raising her voice and tried brain washing me. I told her I would like to file a complain and she hung up. This company really needs to get their act up.
