MTN - shocking customer service

On 26 April 2025 I did a change of contract ownership at the Canal Walk branch in Cape Town. 3 May 2025 I visited the branch and I was informed the change of ownership hadn't taken place as yet. I had previously attempted calling the branch but my call was never answered, apparently calls are rotated by staff. I was given the consultant's direct number. 7 May 2025 she made contact with me and I was informed there was an issue and we had to redo the verifications. I asked her to confirm if all was okay on 9 / 12 / 13 May 2025 and no response. I am highly disgusted with this service.
