Complete lack of customer service from DSV couriers

Honestly 1 star is way too generous. I've been waiting 2 weeks for the delivery of a parcel from a Cape Town based company to a Cape Town address. I've tried to make contact with the DSV call center only to receive rudeness from consultants after waiting 15min to speak to someone. No apology before having them hang up the phone without helping me. The message I receive via email is "no one is home to receive the parcel" - funny since I live in a security complex with security at the gate 24/7! Extremely frustrating.
