Dialdirect insurance unprofessionalism!!

Despite me being claim free for 3 years with them, Dialdirect send me an email, stating that my premium will increase by 40%!!!! I emailed them objecting to this RIDICULOUS increase, especially because I had NEVER claimedfrom them in 3 years?? Their consultant called me trying to justify the increase; I told him that a manager must call me within 2 days if they wanted to keep my business. It is now 5 days later, and I have not heard from a manager?! They obviously do not need my business. Today I found CHEAPER and BETTER cover for my cars!! I DO NOT recommend Dialdirect insurance to anyone!!!
