VOX Pro-rated Billing. Bill upon line activation rather than upon Modem Receipt

After a really bad experience with another Service provider, we changed to VOX and cancelled the other FIBRE Service Provider. I am giving VOX 3 stars only because their communication from most staff was acceptable. However two issues: 1. You could save a lot of Frustration, time and Money for the Infrastructure provider by finding out if a complex has Openserve or Vumatel Infrastructure before placing the installation order. I picked Package VOX 250/100. If VOX had just established that the complex had Infrastructure from Vuma they could of saved 2 weeks of frustration for Openserve and myself. 2. Vuma Activate line on 27/11, Modem received 02/12. Receive bill. They Charge us from time Line was activated. I call accounts, speak to Palesa who clearly does not understand Pro-Rata billing and stands behind "POPI" and declines to give a clear explanation of why I appear to be overcharged.
