Undeliverable MTN package and no means of contacting Courierit

I was waiting for an MTN delivery, however my ID copy via the computer screen was not accepted by the device, also my driver's license and passport. I was then unable to accept the parcel.

The driver promised to deliver the parcel yesterday (following day), but cancelled the delivery still as ID not valid (he did not bother to contact me), however, I obtained a copy of my ID document waiting for him to arrive. Why did he cancel the delivery without even confirming.

When he was here, he was extremely curt and rude rushing me constantly saying he has many deliveries.

I tried sending a Whatsapp to RTT, Courierit only to be ignored, I phoned RTT and Courierit to sort this out, but phones are dropped mid call. I emailed and the email bounced back saing it does not exist ("***" <***>)

If only I can get through to at least someone, I will be able to sort this out but I have my hands tied, I can do absolutely nothing.
