Poor service

My experience with MiWay insurance has been disappointing to say the least. They ask me my details and then still get the details wrong and critical details at that. I contact them via email to rectify their errors and they phoned me but i was busy so asked they contact me back at a specific time as that is my lunch break. They can't get it right to phone me at said time, still phoning at odd hours while I'm busy and can't answer my phone. By chance they caught me on Friday evening where I could and did answer my phone only for them to hang up on me when I answered. I am cancelling my insurance with miway as if they can't capture basic details correctly and can't phone when their client gives them a specific time then how will they ever manage to handle a claim accurately?
