Unable to Cancel Web Africa Broadband Service

I have experienced the worst service from Web Africa that I have experienced in many years. I have moved to Ireland and no longer need a broadband service in South Africa any longer. The Web Africa online portal does not allow you to cancel via e-mail or telephonically, and re-directs a user to a Whatsapp chat. I've had no success in getting hold of an agent on 2 consecutive days using the Whatsapp Chat. The App also has no numerical option for Cancel. Today, after my 3rd day of Whatsapp Chatbots I've had enough. I've been in a Whatsapp chat with chatbots and agents for over 2 hours, and finally just when I thought I might have a response, I was told I am non-responsive and was directed back to the menu!!! It is ridiculous that we cannot make contact with Web Africa other than via Whatsapp, and that we cannot cancel our service via the online portal!
