Incorrect charges — now scheduled for cancellation. Waste of my time.

I have been having a horrible experience with this company. I called to install fibre in my property, in an area where it hadn’t been installed previously. The person on the phone said that they had a special where this would be free, as long as we used their services for one year. I agreed to this installation. As I was already a customer and had the fibre installed in all the apartments in the property, I didn’t see an issue. A few days later I received an email saying that this fibre could not be installed. I left it, since it wasn’t a huge need, and thought I would find another solution. Then, a few days after that, I received an invoice for the installation, despite the fact that — 1. This was said to be free and 2. The installation was cancelled by Webafrica for unknown reasons. This money was debited from my account. I called the em to reverse this — and the after explaining everything, the person on the phone said he would reverse it, but it hadn’t shown up on the system, so it would take 24-48 hours. Due to this debit order, my account was in negative balance and I needed to make payments, so I called the bank to reverse the payment, thinking that it would be fine since the amount would have been reversed by Webafrica anyway. Unfortunately this was not the case. The fibre was stopped and the amount added to my month end invoice. I have now tried to call multiple times but it seems nobody knows what charge I am talking about and cannot reverse it or reinstate my fibre. It is now scheduled for cancellation tomorrow. Their WhatsApp service is completely useless as well. This has been a huge waste of my time.
