PHP SoapClient with timeout

SoapClientTimeout.class.php

<?php
//Drop-in replacement for PHP's SoapClient class supporting connect and response/transfer timeout
//Usage: Exactly as PHP's SoapClient class, except that 3 new options are available:
//	timeout			The response/transfer timeout in milliseconds; 0 == default SoapClient / CURL timeout
//	connecttimeout	The connection timeout; 0 == default SoapClient / CURL timeout
//	sslverifypeer	FALSE to stop SoapClient from verifying the peer's certificate

Please , as I pass parameters to this class after that I declare ? example :

$fecha_soap = date ( 'Y-m-d\TH:i:s' ) ;
$xml = '
soapenv:Body
tem:ConsultaSaldo
tem:consulta
poin:ClaveVenta0104/poin:ClaveVenta
poin:ComercioId2783/poin:ComercioId
poin:FechaHoraTransaccion' . $fecha_soap . '/poin:FechaHoraTransaccion
poin:PasswordPpay35085*/poin:Password
poin:TerminalId197/poin:TerminalId
poin:TransaccionId1/poin:TransaccionId
/tem:consulta
/tem:ConsultaSaldo
/soapenv:Body
' ;

$wsdl = "https://col.pointpay.net/WCF/PointPay.Bridge.webService.WebServiceCO.svc?wsdl" ;
$location = "https://col.pointpay.net/WCF/PointPay.Bridge.webService.WebServiceCO.svc" ;

$soap_client = new SoapClientTimeout($wsdl , array ( "timeout" => 10, "connecttimeout"=> 15 ));

$imagen = $soap_client-> __doRequest ( $xml , $location , "ConsultaSaldo" , 2 , FALSE );

print_r ( $imagen ) ;

Fatal error: Uncaught exception 'Exception' with message 'Resolving timed out after 12 milliseconds' in /var/www/html/recargas/index_soap.php:131 Stack trace: #0 /var/www/html/recargas/index_soap.php(179): SoapClientTimeout->__doRequest(' ...', 'https://col.poi...', 'ConsultaSaldo', 2, false) #1 {main} thrown in /var/www/html/recargas/index_soap.php on line 131

Response is always false. Looks like it does not wait for response at all.
