MTN THE WORST SERVICE!!!!!

My husband and I have a contract with MTN. We upgraded recently and got a iphone 12. The iphone we received worked for a week and a half as it had network issues. We sat with that faulty phone for 2 more weeks while waiting for something to happen. MTN never even alerted us when the courier company would be picking up the phone. Courier company just magically appears at our gate and in a rush i send the phone off without the charging cable. 2 weeks later I am told that abolutely nothing has been done as they do not have the charging cable in the box. 2 weeks later !!!!!!!!!!!!!!! Paying over a thousand rand a month for almost 3 months now for a phone that we simply do not have and have not been able to use. The worst service ever! *********** staff! its really become ridiculous. I will be taking this even further to MTN. We will require a credit on the times we have paid MTN for a phone we did not have. We have been MTN customers for a long time now and really we are ready to take our business elsewhere. we use our phones for emails, and business. This has had a big impact on our business. No one can get a hold of us. Today I am told the phone is going to the supplier now and there is a turnaround of 3-5 days to get a phone. After I was told a week ago that the phone was with the courier company making its way to me. So dissapointing.
