Telkom's doesn't assist and takes money!

I completed a cancellation request on the 28th of June 2018 at exactly 17:16PM with their online Self-Sevice. Because you can not go through the stores anymore. Having gone through the process correctly and got an email to notify of the cancellation request. I still received a statement for July 2018. Thinking it was to pay for the month prior, I accepted. I send through a message to their contact center and spoke with an agent called Cindy Goliath via email, who requested I send through the cancellation ref number and a copy of my ID, which I did immediately. Now in August, I received another statement to say I need to pay them again. It is absolutely BS, that they do not have a number to phone, but you have to go through an online chat, where the agents don't assist and you wait hours! On top of it Cindy Goliath, never contacted me back, even when I sent her another email to request what is going on. If my money is being deducted once again, I will take this further. No way am I ever going through Telkom again to purchase a service. The customer support is **********! I want my money back with immediate effect, as I have cancelled my service!
