Horrible customer service

Bad customer service. I enquired about doing a number change in August. All the call centre agents sent me from pillar to post. Eventually I got a guy called Sipho Hlatswayo to assist but i didn't have both SIM cards at the time. He requested I call back when I have both SIM cards. I've been calling since the begining of September. Every week i call and I leave a message for him to contact me but till today nothing.

I call last weekend and the call centre agent said the supervisor would e-mail Soon I and CC me in the email. Till today I havent received the email from the supervisor not received a call from Sipho. How hard can IT be to do a number change
