Dishonest and manipulative

A few months ago an agent representing Vodacom came to me practically begging me to sign up to fibre. I said I was not interested as we have a set up at home with ADSL plus the two portable modems (through Vodacom) which suited us fine. He raved about the fibre basically not listening to me so I gave in and did the application ONLY with him via his tablet. I repeated myself several times stating that this was NOT me asking for fibre at this stage, but only doing the application. He said did his thing on his tablet, asked me to sign electronically and I thought that was the end of it. A few days later I received notification that my application was approved (after all, I have been with Vodacom since 1995?) and that the "order was processed" and that I could expect delivery of the fibre package. Keep in mind that now this agent is nowhere to be found so I have no way of contacting him to question what was going on! I received the package and followed the instructions (thinking that seeing that it has been delivered, I may as well go ahead). I recall the agent assuring me that fibre would be live either the end of August, but no later than end of September (which has come and gone). I noted an increase in my debit order at the end of August, but since I do not have the pleasure of receiving my statement, I had no idea where the extra cost came in so I travelled to George where I was told to "phone fibre" as they could not help. Phoned, and I was told to go to the branch!!! By now I was cheesed off, but still maintained my demeanour. The LTE that was supp**** barely worked so we continued using our ADSL and mini modems as per usual. When I received notification that the next debit order was going to be around R500 plus more, I got angry! I phoned the call centre to cancel and to ask for the additional costs to be reversed immediately - I was told to go to the branch so in the car again travelling R300 petrol out to go to the regional branch. Get to the branch and guess what? They can't help me so I must PHONE! By now I am fuming - not only are you wasting my time, but my money too! I phoned from the parking lot saying that I had the setup with me and I was told that it would be collected from me within a few days - it is still here a MONTH later!!! And the cherry on top is that the additional higher debit order went off! I flat out refuse to be manipulated by a company who I have supported basically from when they opened in SA and demand that ALL the additional costs be refunded to me immediately! (failing which, I will take matters further legally and publically!) Only reply in WRITING so that I have hard proof of what has transpired.
