Dont use Supersonic for Fibre - worst service ever

Logged a call almost ten days ago on the phone - this after I also logged it with them online without any response. I need an extra wifi extender . They told me the turnaround time is 48 hours and when I eventually after an hour on the phone with Mokhelo and Moses today got to speak to a person I was told the technician is booked for 1 February - which is more than two weeks after I logged the call and with no communication from them. You cant speak to a manager and the call centre agents cannot make a call. Very poor service especially during this time that all of us have to work from home and rely on Fibre and service from a service provider we pay a lot of money to. I am not happy and looking for an alternative provider. I am sure not even this complaint will elicit a response from them. When I joined them their service was fantastic - what happened since then??
