We paid for the fastest World Air option, 1-3 days. My parcel was supposed to arrive either today or tomorrow. Tracking says now that it won't arrive until Saturday - at least 4 days. Saturday is my wedding. The parcel is my ring. Saturday is too late. I've been trying to reach them for 3 days. I've been passed around to 5 different departments, and the online customer service options are an absolute joke; I've been waiting 3 days for a single reply from 3 different online DHL services that claim to reply "typically within minutes". This is hands-down the worst service I've ever had in my entire life. What a joke of a company.
