Fiber line locked-in without contract/concent

I find myself in a situation where an application that was presented to me as a 'pre-approval' has now a changed status of a signed quote. But after the sales person was at my house and ASSURED me that this is NOT a contract but only a 'pre-approval', Vodacom phoned me every month from March until at least July to sign a contract with me for fiber. While they have my fiber line locked-in since Feb 2018. Nobody gave Vodacom the VT number to lock in my line - I did not have that number until early Sept 2018. I had to get 'n Vumatel guy in for that. The magic of this nightmare is, my fiber line was faulty since installation and was only fixed beginning of Sept 2018. So why on earth would I have signed a fiber contract if I knew my line is faulty?? No one in their right mind would do that and that was my reason from March until July why I cannot sign up for a fiber contract. O yes, although the Vodacom people dealing with the HelloPeter complaints assured me there is no R1,725 payable to release my locked-in line and that there is now no reason why my line should not be released (since everything has been cancelled and deleted that must be), I am STILL struggling to get someone to de-link my fiber line from Vodacom. Please, get the right person to press that de-link button and then phone me and email me that this HAS BEEN DONE! This is now going on since 12 Sept 2018 and I am really fed-up speaking to people not knowing what they are talking about and hearing a different story every time and have to repeat myself with every call.
