Using a WSDL File to Submit XML file through web service

I am using ASP.NET and C# to display a form for someone to complete and submit a request to an external company on a button click. The company provided a WSDL file which i was able to import into my Solution as a Web Reference. Once I added the reference it generated a bunch of classes which appears to create an XML file and from what I understand is what I need to do. I given an example of what an XML file submittion looks like but I am a little confused on how to the web reference and submit the request.

Here is the WSDL

I am trying call the complextype (method) ClaimSubmittalRequest This is what I was able to do in my C# code (get and set the fields):

        var submitClaim = new ThermalKing.SubmitClaimRequest
        {
            claimLanguage = "ENG",
            serviceVersion = "1.0",
            claimType = "PARTS",
            failureDate = new DateTime(2014, 11, 26),
            faultFound = "PERFORM A FREE INSPECTION"
        };

        var submitParts = new ThermalKing.eachPart
        {
            partNumber = "1234",
            partPrice = 100.78,
            partQuantity = 17
        };

Here is what the example XML File looks like:

<soapenv:Envelope xmlns:soapenv="http://ift.tt/sVJIaE" xmlns:xsi="http://ift.tt/ra1lAU" xmlns:get="http://ift.tt/1yEtCDJ">

How can I call the Complex Type Method in my C# code to send the request to the external company? Or is it easier just to create an XML file manually using C#?
