Webafrica service and after service

I have app**** for Fibre in November 2020, the money was debit from my account and the fibre was only installed January 2021. Thereafter we had struggle to get the fibre working after router was delivered. End of January payment was taken of my card again and February no working fibre call was logged 15or 16th February 2021, I came back home and still no working fibre. Tried calling numerous times and after holding the line for 45 min they answer then the call was cut. Beginning of March again they debit my card with the payment while still now working fibre although it still show active at Webafrica. Then the debit was return and I receive a sms telling me the service was suspended due to returning debit and I was happy with suspension. on the 16th of March they debit my card again then I call and after 25min on the line the call was finally answered. I explain my problem and then they send me a link in order to do the cancellation. Now while doing the cancellation get notice that I need to pay the installation fee of R1840-00 and the router if I can not sent it in in 21 days. I am not at the house where the installation was done i am in Gauteng and will only be back end of October 2021. I will not pay anymore fees for a service that is not working as well as for no service assistance . taking money without providing any service is theft.
