Mtn is darkening my day

My cell phone was ****** on 10 June 2018. I contacted Mtn on 11 June 2018 to block my Sim and blacklist my device. On 12 June 2018 at 13H30, I went to the Mtn store at the Mall of the South to do a Sim swop, and was told that the new Sim would be active by 6pm that evening. At approximately 15H00 I received an email from Mtn-Verified asking me to click on the link asking for confirmation to proceed with the Sim swap. The link to http://siweb.mtn.co.za/public/simSwap.cfm?reason=sim_swap&token=********************** does not work!!

I phoned the call center to advise them of this and was told to ignore the email, as they have never heard about emails from Mtn-Verified, and that I should ignore. The next day, my Sim still was not activated. I phoned the contact center a few times and was told that it would take up to 24 hours for the Sim to be activated. After more than 24hours, I managed to get hold of the Mtn store and the guy said that the Rica had failed and that the new Sim would be activated in 10minutes. Unsurprisingly, it was not. I phoned the store again and he told me that everything looked fine on his side, but would check again and phone me back. I'm still waiting...

I called the call center once again, and was told to phone activations. The lady at the activations department told me that she would send an email to the Network department to manually approve the Sim swop, and it would take 2 - 3 hours to resolve. Again, an hour later, I got an email from Mtn-Verified asking me to validate my request. THE LINK DOESN'T WOR**** I called activations once again, and was told that the Sim swop was done at 14H18 on 13 June, and I must wait for the new Sim to be activated. I'M STILL WAITING....

Can no one at Mtn resolve my issue???
