Vodacom Fibre Lack of service

We have a home business using Vodacom fibre and that part is all well. Unfortunately I have now asked for voice as well and being a business I asked for the number porting to be a seamless affair seeing that we are a business. Unfortunately that didn't happen and we found ourselves with a telephone system with customers not being able to call us, but we being able to call out still using our old provider. Eventually they got part of that working until we asked for another line to be added as we have a base station and 2 portable phones. That's when everything started getting worse. My technician has been phoning support constantly and now it's 3 weeks and we receive calls but cant make calls. I don't know who to talk to anymore, went to the Vodacom store in Clearwater mall as it is listed as a business centre and that didn't help either. Just got blank stares. To add insult to injury, I have now been billed for installation by Vumatel, which was supposed to have been included on the promotion when we signed up and not to mention that from September's fibre installation we are yet to receive an account. That also after countless calls. I really need this sorted by someone and not just another person on the other side of the phone. Surely a company the size of Vodacom has someone that can come over to the physical address and setup our system and if the hardware is inadequate, tell us what we need so we can get this solved.
