Took my money 7 weeks ago, no device received

I ordered a Lenovo Miix 320 6 weeks ago on the phone (10213). On the 17th of September the courier company bought a device to my office. I signed and upon opening the device, in my cubicle, I found that the wrong device was sent (a Toshiba laptop). I called 10213 immediately and the guy I spoke to said that it will be collected before COB and he confirmed that a lady from Telkom had given the courier company the wrong information. Noone came. I called again on the 18th (Tuesday). Spoke to Cameron Perumal and he also said it will be collected COB. Noone came. Wednesday and Thursday I called and all the agents systems were offline. Friday I spoke to Njabulo who rudely told me that his system is the only one that is offline and I will have to call and wait again to go through an agent who has a system that is working. I called again same day and spoke to Gugulethu who promised, after speaking to her manager, that it will be collected on that Friday. I called again same day around 2pm just to ensure that someone will definitely come through and spoke to Roxanne Reddy who said she cant advise when the device will be collected and cannot see any case created under my profile regarding this matter. Friday eventually came to an end with no one coming. During this whole week I have been told to contact several Telkom number and the courier company without any luck. On Tuesday the 25th I tried again spoke to Mbali who also logged a case. Wednesday, called again, spoke to Nompumelelo. She too logged a case. Then on Thursday/ Friday I spoke to ryan who had me holding close to 40 minuts trying to find a resolution only to tell me that I must send the device to my nearest store. Saturday I went too Maponya mall and Southgate mall and I was told they cant take devices that were not purchased at the respective stores. Called again today the 1st of October 2018 and spoke to Thabo Nzama who says he sees no cases logged for my profile regarding this case and he will log one that will definitely reflect on the system and he will escalate to his manager - Andile Dlamini. He told me to wait aa further 48 hours. Now after waiting for two weeks I doubt that it will be logged and once again no one will pick it up or bring my order. I don't know what I must do anymore

It occurred on: 17/09/2018

I want an apology for all the calls and driving around. I want them to pick up their Toshiba and cancel my order for Lenovo Miix 320 because I just cant deal with Telkom anymore. I dot want to pay any cancellation fees because I did want the device they failed to provide because they say it is out of stock yet they keep advertising it

I look forward to your prompt response on this matter.
