Telkom WiFi deactivated yet charged for it

I visited Parow Centre Telkom branch to cancel my WiFi, I was fully aware of the notice period but I did not expect was that my WiFi would be immediately deactivated and that I would still be charged for a notice period where I did not even use the WiFi. Yes today the debit order went of for the full amount instead of it being amended accordingly. Well I will be logging a complaint with the ombudsman and taking this matter further. I even sent an email to them indicating that I am not happy with the fact that I will be charged for WiFi I do not have access to after cancelling yet nothing was done, not response was sent or attempts to reach out to me to fix this issue and this is almost a month later.
