Vodacom Fibre charging me for a service I have never used

#VodacomFibre I ordered a Fibre Router which was delivered but was not installed, Vodacom Fibre technician blamed the Fibre cable line technician from Open Serve and vise versa. I then cancelled within 2 weeks not having used any data. I phoned in 3 times requesting Vodacom come collect their devices and I am still waiting 6 months later. I was assured I would not be billed for this service and it would be collected from my premises. July 2020 I was billed R600 for a service I did not use and was advised I would not be billed (keeping in mind the monthly cost of the internet was advertised as R450 and not R600). I have called and escalated and still nothing has been done, not even an email to say they have received my query and no devices have been collected. I have been inconvenienced when they tried to install (because it was not even installed, not even the free 100 gigs internet) and now an even bigger inconvenience to cut all ties with Vodacom. I would in my opinion without prejudice not recommend their service, unless you like dealing with companies that don't take you seriously but they are happy to take your money. The Vodacom Fibre department does not even have a direct line to the Billing department. Things are not being done properly I have been charged incorrectly and I have to use my airtime and my time to sort this out when I am not the one who has made the error. I have been trying to cancel for 6 months now and I am worried they will incorrectly debt my account end of August 2020 as well which results in another refund to me. Very disappointed by such a well known companies service, my first time with Vodacom and what a terrible experience it has been.
