Radio Silence from DHL when you need them

This in reference to AWB ***. Package is sitting with customs after all duties paid and information submissions were all done in good time. DHL has app**** radio silence and have not shown any intent or willingness to assist with the situation. While I understand that it is with customs and has been for a long time, radio silence is not a good look. I have been unable to phone my contact (no answer) and she doesn't reply to my countless e-mails. At my wits end and therefore turning to Hello Peter.
