Extremely bad Telkom customer service

<p>I had a mobile internet contract that ended in September 2016. I notified Telkom through their cancellations department of my intention to cancel in August to prevent them from billing me on a month to month basis after the contract end date.</p> <p>I received a confirmation email that my cancellation notice was received, but have been billed for this cancelled contract every month nontheless. I have tried several channels to remedy this since October 2016, but to no avail. I keep getting apologies and promises that it will be sorted out, but at the end of the month, the money is deducted again.</p>
