Vodacom Fibre has not been installed after 9 months of paying.

I took up a contract for vodacom Fibre in April 2020 after I saw the ad for R449 per month. I have been calling vodacom every month since April 2020 to follow up when they will install. It is now December 2020 and I have no Fibre installed. Vodacom has been deducting R599 sometimes twice a month for 100Gigs at a time. I have spoken to over 15 consultants on the phone who all give me a reference number and promised to respond in 7 days, never have I once in the 9 months received a call from Vodacom. Today I requested a cancelation of my Fibre contract request and the lady on the phone refused to give me a reference number. She told me she will send me an sms. But I have not received an sms. I asked her if I can have a number or email address to escalate my matter and she refused, told me she's the only one who can help me. I am tired of calling vodacom every week. Please help!
