Horrible service from MTN call centre

I have been on MULTIPLE calls since Thursday 26 October 2023, sent MULTIPLE emails since Thursday 26 October 2023 and been directed to MULTIPLE departments since 26 October 2023 in order for me to cancel an online upgrade I did on Thursday 26 October 2023. I am currently on a call, being transferred to a different department (again and without being told, just placed on hold and transferred) to STILL find SOMEONE to assist. Mtn direct can't help. Retentions can't help. Upgrade department can't help. Customer services can't help. I will not be signing for this phone AS I REQUESTED THE ORDER TO BE CANCELED. Philisiwe at customer service was the ONLY person to ever TRY and assist. Absolutely atrocious service from MTN. Now my number has been taken down for someone to call me after 1pm, when dsv is on their way to deliver the phone.
