No Response on requests

I received my updated policy because it is renewal time and increase time. This will never be missed. I requested that the value of the property insured, be reduced. I have send 2 requests and not response from Momentum. They are very quick to send increase letters, but when you ask them to reduce a value, then nothing. I did tell them earlier this week that I will come to HelloPeter of I do not get a response. No response received.
