Complaint Mondo / MTN

I upgraded my contract with MTN in December by making use of their widely advertised online facility. Little did I know that this is in fact not MTN but a subsidiary called MONDO. After waiting 2 weeks for delivery of the handset, they delivered the incorrect handset. I called the help line and held on for 1:04:08 minutes to be told I need to hand the phone in at an MTN direct store. I did this the same day 31/12/2020 at MTN Bayside Mall. They gave me an IRMS number and told me someone will call me in 2 working days to cancel the upgrade and we can redo the contract. Today is the 19 January 2020. I have made calls to Mondo Senior Management Fahana Nepaul who said they were going to make this a priority. Then I called MTN they said Mondo must handle this and they cant help. I called the store to find out where the handset I handed in is, to be told by Nizar Isaacs that this is Mondo's responsibility to tract this with the Courier company. My new contract is live and running but I still don't have the handset. This was an error or their side. They sent the wrong device. All calls are recorded. How difficult is this to resolve. My contract is with MTN. Surly they must manage their brokers in terms of Fais and TCF. In all my life i have never had such bad service ever. When you contact them on Email, or Facebook, they tell you to Direct Message them. You never ever get a response from these messages. I have now reported them to Icasa and the Consumer Ombud to try and resolve this problem. Trust me when I say, no-one at MTN give a **** about Customer Service they are a big corporate that is all about their bottom line. In a month after all of the above. Not 1 person has tried to even call me to discuss or try to resolve.
