Heavily delayed service with no updates communicated

I app**** for a Telkom LTE sim card for my mother to supplement her data usage in order to use Google classrooms to conduct her lessons during the lock down. I recieved a notification from Courierit yesterday morning and this morning to say that delivery can be expected anywhere from 8am to 5pm with no further update. I had called their Johannesburg branch yesterday numerous times and numerous times again today with no answer, as the delivery is for Roodepoort. I resorted to calling their Pretoria branch to get an explanation or a definate ETA. They advised that they are operating on skeleton staff and are under pressure for dispatching orders. There has still not been any communication from them. At the very least one should communicate should there be delay.
