Bad service

I'm not happy with the way this company operates with their customers. They dont call me to communicate about what they need regarding my comprehensive car insurance information instead they decide on their own to make me a vehicle debt protection without my approval. I sent them my comprehensive car policy proof they don't call to say it's incorrect instead they insist on opening this vehicle thing I don't want coz I have a comprehensive car insurance. This Is not the first time I have an issue with this Company. Now they added money to my installments without my concern. They better call me coz even wen I call them they hang up on me
