Terrible customer service from MTN

I requested a port from Telkom to MTN around 2 days ago. Somehow the port went through and the sim got deactivated. Two days later after numerous phone calls and complaints I am still waiting for my sim card to be re activated. Every single time I call I get the same response that the technicians are working on it. Absolutely disgusted with the service I have received and I just signed up for a new contract with MTN which I am now seriously regretting if this is the kind of service I am going to receive!!!
