Not cancelling my account

On the 7th of February I phoned Telkom in order to cancel my line as I app**** for fibre and moving away from ADSL. I was told that this cancellation procedure is now handled online and I must go to the Online Portal. I completed the cancellation and received an email: "Telkom SA: Cancel Service Request" which shows my number to be cancelled.

Now on the 9th of April the telephone line is STILL LIVE and I am being billed for it. When I phoned 10177 I was just told to complete another cancellation request and give it 30 days. I already gave 30 days notice OVER 2 MONTHS AGO! Why must I still pay?
