Vodacom Cellphone Insurance

Vodacom has been the worst experience of my life. Their cellphone insurance initially took an amount money from my bank account which I wasn't aware of. Claiming that it will benefit me in the long while. I missed one payment since I was in the process of changing my banking details and apparently I was never registered for their cellphone insurance. Their system is not picking up my personal details, while I have been paying them for approximately a year now. They have a poor service, and I'm also not certain why this company doesn't help me at any Vodacom store, and be forced to call and trust people I have never seen with sensitive information. I'm taking this to the police or social media because it's not okay to treat people like this.
