MTN Online upgrade gone wrong- Poor customer Service

I have MTN Silver 6GB data contract, I app**** for an online upgrade on the 28th April 2024, this is when the nightmare began. The upgrade was approved on the 30th April, but since then it has been stuck in the system. I get messages every couple of days saying that something will be delivered, I don't need anything delivered, I have the sim card already. I phoned the call centre multiple times, I have gone into a store, I have sent emails to customer care and customer complaints and nobody bothers to get back to you, here is my reference number that I logged on Sunday.

Reference number: 563a470a-c954-4d54-a517-f2df949786d4

MTN Upgrades tell me that many 3rd parties do their upgrades and the order is open and they cannot help me.

24 days later and I have not answers. MTN this is shocking customer service, your call center is very unhelpful, they put you back on hold and you land up in the same looped menu again an again. I am posting here in desperation

DO NOT DO AN UPGRADE ON MTN'S ONLINE PORTAL.
