MetroFibre stole R4000 out of my account and won't pay me back.

I've been with MetroFibre for about 6 months. It took more than two weeks to set up my WiFi. I was on the phone for over six hours just so they could active my WiFi. On the 3rd of May, 2024 they wrongly and without reason took over R4000 out of my account. It's been 3 weeks and I have called more than 50 times, and they still haven't returned my money. They keep making promises that I'll get my money, and that management will give me a call, but it's all been lies and they have still not paid back a single cent! They do not care about their customers at all! Please do not even consider them when looking for WiFi.
