Received a partial delivery

Received a partial delivery from DPD with item missing from my order. After sending an email reply saying they were checking with logistics partner, support has completely stopped responding to any follow-up emails. Their contact number does not work at all. Expecting an update or resolution is impossible with this unresponsive support.
