Upgrade nightmare

In December of last year, i decided to upgrade my contract with Telkom mobile. I selected a package that suited me online and filled out an upgrade request. A person only called me weeks later to process the upgrade and assured me that my device would be delivered by the 7th of January 2021 at the latest. This was a few days before Christmas. On the 8th of January i had to call telkom to change the delivery address, as i would be back at work from that Monday. They then informed me the delay was due to the fact that they did not have stock of the device, and took down my work address. On the 27th of January, they sent the device to my home address. When i contacted the courier company to inform them that i would not be available at that address, they informed me that the only thing they could do would be to send the device back to telkom. On the 29th of January i contacted telkom regarding the shipping issue, i was told that the order would have to be reprocessed and that would take 5 to 10 working days. On the 9th of February, i called telkom to check on the progress of this and was told that nothing had been done on that order and they did not know why. I was quite annoyed by this point and cancelled the order. This was the worst service i have experienced
