Poor Service, cannot even reach them when I call in

Absolutely poor service - I am a client under a group scheme which I was informed about a couple days back. I requested that my policy be cancelled as it was an added benefit as a result of a Solidarity membership. I cannot get the representative to respond on email based on my enquiry and cannot get through to the group scheme department using the call center or dialing in using the number listed on the policy for enquiries - it just rings. This is absolutely poor, I havent even been a direct client and given this service I doubt I ever will be.
