Horrible service from Nelspruit Aramex

I normally have excellent service from Aramex, so I used it to send a parcel from Durban to Barberton. The parcel was collected in Durban on the 3 Dec 2018 and delivered to Nelspruit on the 4 Dec 2018, where it was handed over to a 3rd party for delivery. After numerous attempts to get hold of someone in Nelspruit, I called the Durban branch and spoke to someone there. He took down my details and said he'd call back, but I'm still waiting.

I sent an inbox message to both Aramex and Aramex Drop Box on FB, and received a few responses there. Later received a call from the 3rd party delivery company in Nelspruit. Lady asked to speak to someone, who wasn't me, so I said she had the wrong number, and she said she was calling because of an Aramex delivery. Told her that I was also expecting a call from Aramex. Turns out she wanted to speak to me.

Apparently her driver went to Barberton on the 4 Dec 2018 and couldn't find the address, so returned the parcel to the depot, coz they said they called the number on the waybill, but no one answered. So why then, didn't they call me (the sender) and tell me that they can't get in touch with anyone.

Also, Barberton is a small place. The address that I provided is for a business, which is on the main street in the town and it's a big building. Very difficult to miss. And if for some strange reason, you do miss it, there are 3 separate entrances on 3 roads!!!
