VODACOM FIBER ***** !!!!!!!!

Vodacom Fiber call center contacted me last year saying that they can contact me when fiber is available in my area - They never did ! You know what they did is they posted their wifi rooter and then asked frogfoot to install the fiber in my house. (this was send back as I do not accept any parcels if i did not sign or requested for it) I dont mind that frogfoot came and done the installation I thought this is part of the deal to sign to any and again ANY service provider. I confirmed with the frogfoot installer that this is a free installation and I can chose any service provider - he agreed and I stil have his contact details to prove it. Now I decide to go with MWEB , vodacom is refusing to cancel their activation to my fiber line without a payment ??? what payment??? I NEVER AGREED TO ANYTHING FROM VODACOM!!!!! this is terrible and by the way *****!!!! Now Vodacom also take their time to actually get proof of me agreeing to their service provider - I bet you cant find it cause it doesn't exists ! Please can someone help me, should I open up a ***** case ? I honestly just want this sorted out the legal way .
