Can't cancel contract

Mi-way are impossible to get hold of and the one phone I did get today - twice my call got cancelled while transferring to speak to their cancelllationa dept. I don't want the mi-way insurance!!!! I got a call earlier this month offerings me a cheaper Insurance but I tried asking more questions after the call via email and no response. Now I'm told I'm a policy holder with Mi-way while Im actually a policy holder already for the same goods with outsurance. Mi-way -I don't want your policy based on a salesman phonecall with no follow up to answer my questions. Cancel my policy immediately
