Overcharge purposefully and won't do anything about it once caught

While checking what customer profile on the WebAfrica website, I have noticed that I was charged R1029 a month for a 200/200 uncapped package. When I signed up, it was R999 but got a R30 increase which I was aware of in March. But when checking on their website, I noticed that the very same fibre package was for R899. So for god knows how long I have been charged an extra R130 than the normal price. I have contacted them via WhatsApp as their bot is totally useless, and it took more than an hour and half to tell me that they wouldn't do anything as that was the price I signed up for (years ago) but I could upgrade/downgrade myself my package to pay the normal price...

So they will purposefully overcharge you for months without saying a word about it and when you notice it they will almost tell you that it's your fault and that they won't do anything about it.

Avoid them, there are plenty internet providers out there that have some respect for their customers.
