Atrocious service and unable to cancel

Garbage attitude and even worse, unable to even understand the problem, let alone fix it. About 2 months ago I started getting high latency in the evenings with their Cell C LTE offering. The suggested solution was to reset the router which gets done everyday since the router is switched off at night. I also access to a Vdoacom LTE account which runs perfectly but they treid to tell my it was unfair to compare their service to Vodacom since "it has different technology". This took denial of responsibility to a level that was frrankly mind-boggling. They then tried to make it seem like my fault because my area does not have great Cell C connectivity. Firstly it DID have great connectivity up until 2 months ago and secondly I did not buy the service via their website but worked with one of their sales staff who specifically said the area was fine. Then this week an "expert" investigated the connection had found that it was fine. Of course they tested it during the day when I have no problems. And they also suggested switching to the WebAfricaTelkom offering. At my wits end I told them I was willing to try that. Guess what? I will have to PAY to get this transferred and this triggered me to go an instantly cancel the account. Of course, the website generated an error when cancelling which means I cannot even cancel. WebAfrica is not only offering terrible products, despicable service but also showing an incredible level of greed, bordering on theft. (FYI, there is no way to contact management. I asked support twice to have this escalated to management level and they ignored those requests. I sent a message to sales reporting this in the hope that it would get through via them but also nothing)
