I was using too much before I then Relocated to a different address. I call them and they advise I need to sign up again. I pay the fee of R395.00 to sign up. I then received a SMS to say the technician is coming on the 21st Jan. The technician called to advised he need to remove something from my previous address as he won't be able to install again. I called too much WiFi to advised and they said that the technician came out they need to investigate. I requested a to speak to a manager and I was advised there is no manager. I then requested a refund and they said I won't be able to get the refund for the new installation they first need to get the equipment.
