Unrestricted APN

I am a Vodacom customer since 1996, and fairly happy. Two week ago I bought 3 data sims that I use to remotely monitor energy meters. These sims needs to be change to have an unrestricted APN. I filled out the forms and send it to documents@vodacom. I phoned customer care to follow up, several times. I found Thulani and he advised me to send a mail to '***' witch i did with the documents again. I know he received it because Thulani phone me back and made an appointment to phone a bit later, which he did not do. Since then I have not heard from anyone and Loyiso is not responding to any mails. I don't know how to fix the problem as Vodacom is not sticking to their own procedures.
