Poor service

I have been a loyal customer to MTN for many years. I am so disappointed with the poor service. I have changed my contract to a prepaid account on 3rd April 2022. To date I have no joy. Been to the store on numerous occasions. I have been calling the customer care as well. It is time consuming to be put on hold and transferred many times and no one can assist. The concern is talking to so many people and no answers. I need this prepaid Sim card urgently as I run an Uber business. I wish there was a solution to the problem.
