I had the same thing happen to me. I had my webite done just in time to advertise it with my 1/4 page ad in the yellow pages. However, the yellowpage company missed my website.
After consulting with 3 attornies they all said if your phone number is right and the message is there then you are only entitled to about 10% discount. If your phone # is incorrect you are entitled to 100% discount.
If the general message of your ad and your phone # is correct i would say negotiate with them to get a better percentage than 10% off the total. Do not try to take them to court if you loose (most probably the judge wil rule in their favor) then you will have to pay for court costs as well.
I know it is aggravating when you pay top dollars for your ad and it is not printed what you have approved.
In my case i setteled with them for 35% off of the total contract.
Good luck
Edward
