I think you've confused the logic here:
if ( is_wp_error( $response ) )
throw new Exception(....);
else
{
throw new Exception(....);
}
So you throw an Exception regardless of the reponse, and this way you never reach the code further down. An Exception always breaks the current flow, and unless caught with "try...catch", it breaks out of the program. For a quick test, try this (mind the curly brackets by the way):
if ( is_wp_error( $response ) ) {
throw new Exception( __( 'We are currently experiencing problems trying to connect to this payment gateway. Sorry for the inconvenience.', 'spyr-authorizenet-aim' ) );
} else if ( empty( $response['body'] ) ) {
throw new Exception( __( 'Authorize.net\'s Response was empty.', 'spyr-authorizenet-aim' ) );
}
// Retrieve the body's resopnse if no errors found
// ...
