Worst experience getting fiber

Not given what was promised. Could not make a payment because of their pre-loaded account via FNB and informed the sales person who said he'll sort it out but still got disconnected, did speak to the sales rep to dispute why I was charged for a temp LTE solution which I made clear I dislike and don't want and it did not work as expected. got charged for an additional month on LTE because their fiber installation was not done in time, now the fiber is installed, and both are down. When I said then cancel a day into receiving fiber and they said I can cancel but I'll still keep paying. As far as I understand, a contract goes both ways, you give a service, I pay, but if you don't, why should I pay. They just want you signed up and then you are on your own. As an extra, I was told where to place the router to ensure signal throughout, now that that doesn't work, I was asked to get an IT guy in to pull a cable back from where it came from to add the unwanted LTE router to strengthen my other office signal. Job half done and now I need to start spending because I'm stuck with this contract.. business like this should not be suppling services to businesses, they seem more suited for home use where people might only mis netflix for a day.
