Fibre Telephone configuration taking forever

I app**** for a fibre internet and phone line on the 19th of February 2019, within 2 weeks, the internet connection was up and running, however I have been waiting for the telephone line configuration since then. Several contacts with Vodacom yielded zero results with the agents not able to tell me what is the cause of the delay but always saying they are escalating the matter; made worse by the fact that I have to be the one who calls again to follow up with no feed back from Vodacom
