Failure to respond to email communications and poor call centre management

I recently joined Miway business insurance. The person who called me when joining was informed and nice. The challenge started when I called their ********** 464 contact number, I was transferred to 3 different people, each one saying let me refer you to this one, they will help. I hold the next answering says hold I will refer you to the next one. I held to the phone and the third person never picked , I held until they drop. I redialed the same happened. I used another number for business insurance they said they will refer me, I held until it dropped. It was my first time in life to experience a call centre being dropped, usually I hold until. Secondly, after discovering that I by the call centre number I sent emails on the email provided which are: ********** and ********** for the past two weeks I have been sending email, the last email was on 15 January 2017. now I do not know how to communicate with my insurance. there are amendments I need to make on my policy but I am now in the dark.
