Bad service

I took a policy with MotorHappy last year and the terms were not fully explained to me. I requested the sales agent to call me again the following day to explain which he never did. So now I wanted to take my car in for service and I was told that my policy is not in force. They refuse to send me the purchase call and again refuse that another sales agent calls me to explain what and how I'm covered???? Every time I call, they tell me they have put in a request for someone to call me! On Monday 08/01/2018 I called their offices and was told my car shouldn't reach 65000km or else I won't be covered! This is the worst company I've ever had to deal with!
