No customer service

I wanted to upgrade but according to Bonitas need to speak to the Broker. I tried to email, it bounced back. The lady that signed me up is apparently gone and to be honest she was good in the beginning but got to a stage where she never responded to any of my emails or calls. I always managed to do what I wanted directly through Bonitas. It is impossible to get hold of them and there is just no real service. I tried a few times. The number I called them on, just took me back to Bonitas main line, Bonitas transferred me to them, which goes BACK to Bonitas main line. Bonitas finally got an agent from Tenda and they will call back. Ok still waiting. I have spent hours on the phone with zero outcome.
