How to remove headers set by Savon? - ruby-on-rails

Question

I need to hit a SOAP service, however, the server won't accept my request but throws an error due to the below header and footer in the request.
As per the logs, the request/response looks like below:
SOAP **request**: http://www.url.co.au/wserv/wslms.php
SOAPAction: "insertlmsdata", Content-Type: text/xml;charset=UTF-8, Content-Length: 938
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="urn:lmsdataautomation" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Body>

</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I have looked thoroughly Savon Documentation, couldn't find anything relevant. Can I configure Savon to not add headers, footer, envelope and just the body?
Basically to ignore the below data:
SOAP request: http://www.url.co.au/wserv/wslms.php
SOAPAction: "insertlmsdata", Content-Type: text/xml;charset=UTF-8, Content-Length: 938
Otherwise, the SOAP server rejects the request. Please help, TIA
Adding the body of the request:
client = Savon.client(wsdl: url, log: true, logger: Rails.logger, log_level: :debug, pretty_print_xml: true, encoding: 'UTF-8')
response = client.call(:insertlmsdata, message: {'lmsinfo'=> {'userCred'=> {'clientCode' => 'code', 'username' => 'dom', 'password' => '#pass' }, 'lead' => {'requestno' => 3, 'firstname'=>'Methyl', 'lastname'=> 'Orange', 'email' => 'methyl.orange#egg.com', 'mobileno' => '55555555', 'keyword' => 'atlanta', 'requestMessage' => 'looking for atlant', 'responseMessage' => 'dd', 'operator' => 'you', 'circle' => 'sydney', 'requestDate' => '04-20-2017', 'shortCode' => 2222, 'category'=> 'DOM', 'city' => 'Sydney', 'destination' => 'Atlanta' } } })
