Amazon api won't remove my products from inventory

I am sending $ feed =

<<<EOD
<?xml version="1.0"?>
<AmazonEnvelope xsi:noNamespaceSchemaLocation="amzn-envelope.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <Header>
    <DocumentVersion>1.01</DocumentVersion>
    <MerchantIdentifier>XXMYMERCHANTXX</MerchantIdentifier>
  </Header>
  <MessageType>Product</MessageType>
EOD;
foreach($skus as $k => $v) {
$feed = $feed . <<<EOD

  <Message>
    <MessageID>$count</MessageID>
    <OperationType>Delete</OperationType>
    <Product>
      <SKU>$k</SKU>
    </Product>
  </Message>
EOD;
$count++;
}
$feed = $feed . <<<EOD
</AmazonEnvelope>
EOD;

      

        
        
        
      

    

like _POST_PRODUCT_DATA _

I get the report result:

<?xml version="1.0" encoding="UTF-8"?>
<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">

        <MerchantIdentifier>XXMYMERCHANTXX</MerchantIdentifier>
    </Header>
    <MessageType>ProcessingReport</MessageType>
    <Message>
        <MessageID>1</MessageID>
        <ProcessingReport>
            <DocumentTransactionID>blah</DocumentTransactionID>
            <StatusCode>Complete</StatusCode>

                <MessagesProcessed>293</MessagesProcessed>
                <MessagesSuccessful>293</MessagesSuccessful>
                <MessagesWithError>0</MessagesWithError>
                <MessagesWithWarning>0</MessagesWithWarning>
            </ProcessingSummary>
        </ProcessingReport>
    </Message>
</AmazonEnvelope>

      

        
        
        
      

    

However, when I check my inventory online and / or download another inventory list from amazon, the skus that I just submitted, the delete request still exists. I am reading and re-reading the manual and I am confident that I am posting correctly all supported by success messages in the report. Any ideas?

thank
