Rejected claim but covered on paper

On Monday the 15th of July I took my car to an approved dealer workshop by this insurance and they inspected the car and they found out that it needed to replace the ignition and I then on the 16th of July submitted the Reports that they needed which are (previous service report,quotation and the inspection reporr)to this above mentioned insurance company. The report findings were I need to replace the ignition lock,barrel switch and cylinder. And this was sent to them as I am covered for the electronic ignition and under this it is stated that "All solid&state control & triggered units where fitted as standard by the Manufacturer". So today they rejected my claim saying that what needs to be replaced is not covered under the policy.
