Instant Checkmate Deceptive billing and unable to find my account. Las Vegas Nevada

I ordered their services thinking it was a one time thing. I noticed the billing continued and called them about it. I left my phone number so they could call me back and after a few mins they did. After nearly 20 mins on the phone they still had not found my account. I told them I needed to get back to work because I was on my lunch break. I asked the person to give me a call back when they find my account. No call back. I was charged for 3 months of services and never used them after the first time because their service was a joke.
