DSV - non service delivery

Just for the record, I had to give at least one star to get to write the review... I upgraded an MTN contract, MTN use DSV to deliver. The day after I upgraded, MTN informed me my parcel is with DSV, who called the same day - Friday 24 Nov 2023. Great! DSV insisted it be me who accepts the parcel as MTN have stringent protocols - fine. I "have to have a copy of my ID, and proof of residence..." lots of rules and conditions - MTN you know... Also fine. So the delivery date (30th Nov - between 12h & 14h - ensure you are there and ready!!) came and went. It is now a week later, and the only time I have spoken to DSV is when I called them (despite leaving two "call me back" messages. Nothing. Nobody has called to say why the parcel was not delivered, nobody has called to re-schedule, not a thing. MTN (for some reason) gave DSV my wife's cell as the contact number - DSV won't even give me a tracking number (I can validate everything they ask...) because I am calling from my own number, not the one they have on record. (The MTN number is for data only and not a normal contract) I have sent two emails to different sddresses and even those go unanswered. Build long term relationships? Not with me...
