Unacceptable service and billing

Ordered internet with Vuma tel through web-Africa, where they were told there is a box in the apartment as the whole complex has fibre installed, they sent out technicians to replace the same working box in the apartment and then informed stated the line was active, the technicians did not need to swap the boxes and then charge R1725.00 for a 5 min job, this is unacceptable and day light *******. The packages also stated that installation, activation and router were free, called the call center to sort it out and no manager(Lyle) has contacted me yet to sort it out and formally explain the situation from their side, this is unacceptable
