Delivery not done on time AGAIN

A Consultant by the name of Tumisho called me last week Friday (01.03.2019) to assist with my upgrade which was done successfully, I believe. He was friendly and mentioned that I will get my device on Wednesday or Thursday (06/07.03.2019). Today is Friday and I have not received even a notification regarding a delay. I need that device to be delivered by latest (11.03.2019) or you can cancel the upgrade. I am not going through this with Telkom AGAIN. The lines are always busy and cannot go through the call center to speak to a consultant.
