COMPLETE DISINTEREST in providing the service

DSV Transport and Courier, appointed to deliver medication for my son in law pitches us at our property and, I assume, tries to ring our intercom which isnt working at present. Before I grab a remote and go rushing outside to attend to them they have pulled off and left. We call DSV to help and give our address. DSV is COMPLETLY UNWILLLING to eben TRY to check on which vehicle came to our address. COMPLETE DISINTEREST. ..........
