Shocking Service with no communication.

I was contacted on 27/11/2023 regarding a Black Friday upgrade special through MTN/Mondo. I continued with the application with Rochelle. This application went fine and she then advised me I would receive the phone between 3-10 working days. 2 weeks go by and I had no response from Mondo regarding my delivery. I contacted MTN who informed me I need to speak to Mondo because they are waiting for documents. Mondo then confirms they are waiting for documents (please note that I was not contacted during this time regarding any documents). I send the requested documents and was then under the assumption all is now fine. On 03/01/3024 I receive an email saying that Mondo are still waiting for one more document. I send it through. Today (15/01/2024) I phoned Mondo to find out what the delay is and they then inform me that my application was the denied and cancelled due to not having any credit with MTN. Phone MYN who then confirms that the application status is still showing open on their side and that there is no reason for it to decline on Mondo’s side. Phone Mondo who then tells me again that they can’t help me because it’s on MTN’s side, all I’m being told is to take out another upgrade application. No, I continued with the application in Nov because it was a special, and now you want me to take out a new one for a higher price. Through all of this, I was not once contacted except for 1 email asking for a copy of the back of my ID. Absolutely useless.
