Supersonic terrible service and lack of feedback

I have never received such terrible service from a service provider. You are quick to come and install your fibre but when I cancelled and asked for you to free my line and send me proof of this on mail I am still waiting 2 months later!!! I have called so many times even escalating asking for a Call Centre Manager or Customer Service Manager to call me back and no one has ever called me.

Just to release my line and send me proof of this in order for Vodacom to come and install their fibre is just a mission for this company.
