Sim Card Recycled

MTN South Africa has simply "recycled" my business contact number 🤬 Without any warning, my business number for over 3 years has simply been given to someone else! I CANNOT BELIEVE THE SERVICE I HAVE EXPERIENCED! The MTN Bedford Centre Store staff should all be fired, there was no attempt in trying to assist me! They simply told me to call 135, what the point of going into a store if not to help the customers? Then when calling head office, I was told the situation would be escalated, but i have not had a single call regarding my very URGENT MATTER! How can you buy a sim card, in your name, follow the FICA process and then because you don't need to buy airtime, they simple give your number away! My business relies on this whatsapp number, my branding and signage has this number, and now I have been told that there is nothing MTN can do to give me back MY OWN NUMBER!!!! When calling the number the phone is off and therefore it is not in use, but they will not even try locate it so that I may do a Sim Swop? NO EFFORT AT ALL TO HELP A CUSTOMER! People take heed, move away from MTN, they are definitely not here to help their customers!
