MTN - Beyond useless!

MTN is beyond useless. I app**** for an MTN Business Broadband LTE 30Gb package in March 2025. It took MTN over a month before even processed my order due to their gross incompetence and then in late April 2025 they duplicated my order. On the 30th of May 2025 at MTN's request I issued an official letter on a company letterhead requesting cancellation of the duplicated service which they started billing me for effective June 2025. Despite my bringing this to their attention when I received the June 2025 billing and requesting they terminate the duplicated service and cease billing for it, lo and behold I receive today my July 2025 billing and they still have failed to cancel this duplicated service and remove from my billing. Phoning MTN is a complete waste of time and money and good lucking emailing them as they running a black hole for mail accounts. They seem to have a Manager for the manager for the manager and no workers who can assist their so-called "Valued clients". Even my supposed "Dedicated Account Manager" does not respond to emails or even WhatsApp messages for that matter and when she does all I receive back are the usual MTN excuses of "We are investigating" but they are more than happy to keep *****ing my money on a monthly basis for a service they duplicated - not me and now I am expected to pay for something I am not even using so that their CEO's annual Salary of R 70.6 million can be financed. Absolutely disgusting and useless organization of the highest order!
