AVOID!!!!!!!!

Absolutely awful, been with this company for 8 years with a multi car policy. It seems loyalty and bringing 2 others on to my policy has caused nothing but pure greed from Diamond, charging me an extra £300 compared to if I go to other companys with 0 loyalty and single car policies. Now been on the phone for 2 hours and they still can't even get my quote correct, when someone finishes their shift they simply hang up and leave you to have to call again, absolute disgrace of a company!!!!

called to cancel my auto renew over the phone however policy renewed. Diamond initially told me there was no call history on my policy but then suddenly found it once I quoted my call history. Acknowledge I requested my cancellation on 22/8 for an auto renewal 10/9, but now have charged me nearly £100 to resolve their error.
