Telkom ADSL Cancellation Billing

I cancelled my ADSL service with Telkom and I am still being billed 2 months later after the service was confirmed as cancelled effective 2018/08/31. The cancellation request went through all the processes and the contract was a month-to-month so there was no outstanding fees to be paid.

I feel this is theft as I am being requested to pay for a service I do not use and haven't used for a while before the effective cancellation date. Going to their store hasn't helped. I've requested call backs multiple times for months now but nothing, and when I call I am placed onhold for an hour or more. I go on their online portal and the service is still there.

I am truly displeased with Telkom!!!
