Still no phone delivered!!!! Worst upgrade experience of my life - Beyond Pathetic

I have had the worst service from Telkom Mobile, upon upgrading my contract online on the 24th of May this year, they have failed to provide adequate service, the first issue was on delivery, they tried to deliver the phone to the incorrect address on the 28th of May despite having a whole field where you can capture the desired delivery address. I had to call them daily to chase the correct delivery, this took over a week, I finally got in touch with the courier company directly to chase Telkom mobile as they were to pathetic to contact me the client back. The delivery finally happened on Monday 4 June, only to discover that they delivered the wrong handset!!!! I called Telkom Mobile yet again to report their mistake, I was advised that they would arrange for a collection and that the right handset would be delivered shortly. The wrong device was collected on the 5th of June, to this day 18 June 2018 I still haven't received the correct handset. Telkom have billed me for a package I don't have and several "team leaders" have failed to sort this issue out, they are based all over, but the issue happened in Durban call centre where several teamleaders have made promises to sort it out yet nothing has happened. Kaylin Fredericks Lungile Zikale, Shaun Pillay, Lungile Mngomezulu, Lorraine van Wyk, Thandazile Dlamini, Lebogang Tshwane, Thembi, Hinsto, Nomvulo Thele, Masego Segoe, Refilwe Malatsi, all incapable of sorting this ****** issue out. All of these staff have been talked to and the issue has been explained over and over and over with no results, the level of pathetic service and passing the buck is really shocking. I have spent over 9hrs on the phone to Telkom mobile day in and day out, this morning again where another "team leader" in the Durban call centre refused to take the call her name is Laychelle she wouldn't provide a surname. Can it really be so difficult to sort out one problem???? You delivered the wrong phone, scheduled for it to be collected but failed to schedule the replacement's delivery... it's not rocket science, it's a very basic thing.
