Worst service

I am trying to change my policy information for the past 3 weeks. I was promised after each time I called that it will be corrected, but guess what, nothing happened! I am really tired and fed up! If I pay the incorrect premium next month I will be even more disappointed! No one replies to my emails, nor phone me back to keep me up to date. Please do something, otherwise I have no incentive in staying with king price!!!
