Unwarranted Increase & Poor Customer Service

I received a letter fromOutsurnace to advise me my policy is increasing by 11.5%. I called today to ask why I have this huge increase. The first time I called the back ground noise was so loud I could not here the person. When I called back the person told me that the increase is due to inflation and climate change. Clearly this is a ripoff as firstly I do not live in an area where climate change can have an impact on my house. Secondly inflation is not 11.5%. I have only claimed two windscreens on this policy and this is not because of my driving but due to the state of the roads in the country. I could not continue the call as there was so much shouting and noise in the background I had to end the call. The gent told me the noise of from out agents changing shift.
