Poor communication

Good day, I recently got an email from hollard increasing my insurance, I have emailed a few times about that and got no response from them. The value of the car has been decreased since the time I got hollard insurance. I also wanted to put my other car with hollard, but after experience this kind of service I will find another insurance. I don't have time to wait until hollard decides to call or email me back, time is money. Please Hollard, You should really do something about your Feedback and Response...
