Appalling service for change of number

On the 4th of may 2020 I made a payment at mtn Farrarmere branch to change to new number. I have been served with stories of them changing over to new systems and what not. That excuse was used countless times. Now they say the number is active on one system but on another system it's not active. The phone keeps saying rica bared. I'm appalled by the service I have received. I have been with mtn for years and have never had this type of inconsistency. It was stated to me that it takes 7 working days and I would have received a new number. I've been waiting now for over 2 months for my new number. The man I dealt with was Reuben. He has been moved to the east gate branch but I have been in communication with him this whole time. I am very disappointed by mtn this service is very unprofessional
