On accepting a quote i was told it incorrect and i can't do anything about it

I got a quote (which i can provide the reference number to) and i just wanted to add a few things on my already existing policy. A few days after receiving the quote, i called to accept it. I was told that my quote is incorrect and that they can't accept the quote on my behalf. I compared this quote to many other companies and accepted this one as i am already with Dial Direct and it was a good quote. I wasted over 1hrs getting this quote and answering questions to find out when accepting it that it is a wrong quote and I can't do anything about it. This is pitiful. I got a quote that i cannot accept!?
