Financial ****-Webafrica

I have been incorrectly billed and contacted webafrica chat via WhatsApp chat, my services ended up being cancelled even after paying the outstanding balance. They said in order for my services to be reinstated I have to pay R1000 and they charged me for a router despite the billing issue. I requested to speak to a manager and I was told a manager is going to contact me. I have not received a call for more than a month and they have now deducted a cost of R2700 of my account which doesn’t make sense. I want to speak to a manager but that has not happened but they know when to bill my account I have been inconvenienced financially with extra charges from my bank for now a negative balance and has affected me on my personal finance. They’re call centre takes hours with no one picking up. This is pathetic service.
