Can Iwyze respond at all????

I have been with Iwyze car insurance for 4 years now, I have emailed customer care and service at Iwyze for them to contact me regarding my premiums which have just been increased although I have told them vehicles depreciate etc and for a review of my policy. You get an automated response that you will be contacted within the next two working days. My first emails to them were 28 March 2018 and again on 6 April 2018. We are now on 16 April 2018 and I have not been contacted in any way. Stunning non existent customer service!
