Non delivery placing customer at risk because help Centre is no help

I was expecting a parcel to be delivered today from dpd and called last week with instructions that it be delivered before 2pm as the facility I work at would close at that time. This morning I received a message the parcel is out on delivery. At 12pm no sight of the courier and I start phoning the help center in joburg from my cell phone only to be told they can't make contact with the cape Town office to check on the driver. I then started calling every 30 /40 min to check on when the driver will be coming as they were going to send a message to the cape Town office. Only to be told every time that there is no feedback. The facility I work at is in a very volatile area and from 2pm I was standing outside waiting for the courier and kept calling the joburg office as apparently you can't call the cape Town office directly. At about 4.20pm a gang of guys came past who by that time saw me standing alone and I had to then walk to the police station for safety. I once again called DPD joburg but no help and eventually left.

Is this the type of customer service you provide by drivers not sticking to time frames and I know traffic can be hectic but 2 hours look after the driver is still not reachable. And then placing the customer at risk of their safety because the help center is of no help either. I am still waiting for a response and I even filled in the online form for a call back No delivery has taken place yet either. Start taking your customers safety serious.
