Very very bad service

I lost my phone on the 9th July on the 11th July I went to mtn do a swim swap for my contract Sim and I was advised that it won't be possible to get a Sim swap as there is a barring on my Sim card, I have spoken to 6 Different call center agents with no luck. Right now I am struggling to get a swim swap they are telling me that there is a barring on my Sim, however when I call the call center they say there is no barring. So the consultant that helped me suspects that it could be because of those ********** devices on my profile he advised me to check if these devices were canceled and was the ***** case resolved, I have been going up and down since Monday and nobody seems to know what is going on. I've wasted so much time and petrol going up and down and not getting any help. This is really unacceptable and I feel like nobody cares to assist me, I went to 3 different branches and called the customer service over 6 times with no jo. I need this to be resolved urgently as I need to do this swim swap, o spoke to Andile, Ezolam that claimed to have opened a ticket but now when I call I'm advised that the ticket was closed by mistake they need to open a new one this means that I have to wait for another 3-5 working days 😠😠😠😡😡 I am really dissatisfied with your service, this is a matter of URGENCY I need this Sim swap done as I use that number for business and my clients can't get ahold of me, I am losing money in this whole process. It's funny how you guys are quick to request for payment but don't have the efficiency to help us when we need help can someone urgently call me on *** to resolve this issue today
