Claim Denied Please Help

On 2/25/12 I witnessed my kitchen floor was wet and when i steeped on the lamination wood water came out of the cracks
and on 2/26/12 i called the plumbers and 3 hours later they found out the problem is the copper pipe coming from the dry wall of the house to the dishwasher.
i stopped the water leak and removed the pipe.
Monday 2/27/12 i called my insurance company * Farmers * and started a claim for water damage and today 2/29/12 the farmers appraiser a farmers agent & inspector came to my house, they checked took pictures i exsplanied what happend they went under the house foundation, since my house is a raised foundation they said its really wet & looks like rot on the wood of the foundation & the laminated wood flooring is wavy..
they told me this leak is a long term leak, which its not this all happened 1-2 weeks in time AT MOST! i purchused my house on july 31 2011. and from the home inspection i have it written that kitchen floor looks good and no sign of deffects or wears. i told farmers to write down for me that with there knowledge when this leak took place since they are saying long term leak... they denied writing a letter when they where by me.
i even asked there inspector, is this possible of happening within 3-7 days he said yes & the laminated wood will cripple even in a day...
farmers denied my claim. and stuck with his knowledge saying this is a on going leak for a long period of time!
they said they cover sudden burst & damage and i told them i noticed the floors wet on saturday i called the plumbers next day & you guys arrived 4 days later, and your inspector said its possible it can happen within 1-7 days and yet he still saying this is on going leak for a long period of time!

this is my first house, and times are really bad and i need help. what can i do? what should i do... do i have any right? any help will be greatly appriciated.
