5 emails and 3 weeks later. STILL NO RESPONSE!

I joined with Miway insurance in September and was told when I had had my drivers licence for 2 years and above, my premiums would decrease. Come October 12, I had had my licence for 2 years. I have sent them 5 emails in a 3 week period requesting they please contact me ASAP to update my account but have not had one call back! I phoned them the one day and was put on hold for 10 minutes before deciding to try send another mail instead. The service is absolutely shocking! If I am not contacted this week, I am cancelling my contract!
