Poor Internet service provider

I am very disappointed in Webafrica. I cancelled a service in January, was advised that its a calendar month's notice. Confirmed cancellation on 1 February on the WhatsApp line with Refilwe S. She confirmed that the account is cancelled. This morning the 1st of March I am deducted R679. The frustration is that there is no telephone contact with billing. I am in line for over 30 minutes on WhatsApp. Also logged the complaint with sales, Wesley Morrison and he cannot give a reference only promises to send an internal email. How can you resolve a problem when contacting the company is so challenging. I would not recommend this service to any friends, family or colleagues. If you have an alternative internet service provider rather try them. I wish I could rate no stars. But that is not an option.
