Disgusted and frustrated with customer service

Canceled my internet account with Web africa on 22 July 2022 with an agent name Nomnikelo and she transfered me to another chat agen name Lisa who confirmed cancelation went through. I was not informed of anything else just that my cancelation is being processed no other communication from these agents or this company. The next month when I already moved away I was billed the entire amount R599 although I already put in a request to cancel. I spoke with another Agent named Fuziwe, who was very rude in the way she spoke saying that " were you not informed that cancelation takes 30 days" I rep**** to agent saying "no I was not informed by anyone of these rules" I spoke to so many agents about the same thing and not one of them had the decency to fully assist or explain anything to me , I asked to speak to a manager I was ignored ,I asked to get me through to an escalation department so I can express my concerns. I was ignored. I called in on their call center number , I have wasted all my minutes on the line and no one picks up ,and when they do they hung up ,always hang up the obly department that picks up is the sales department, and they cant help me since they're ,requested to speak with manager again agent hung up multiple times. Reporting this to the better business beareu is usually the last straw for a customer. Web africa I'm extremely disappointed. I feel very insecure with your company and my needs as a customer have not been met upon cancelation and on going support ,it may seem in their adverts like they're on top of their game .but actually dealing them ..us as customers have no real customer service support ,no agent that is able to fully assist and no escalation/ management to speak with
