Takes my money but provides no service/product

I placed a Telkom order - ********** 63A. The sales consultant told me that I have a 7 day cooling off period should I not want the order any longer. On 4.11.2018 (within 7 days cooling off period) - I requested the order to be cancelled. I cancelled the order/service using the online portal but nothing came of it - the status just stayed on "logged". I have also since called and called and called numerous times to follow up yet no-one is actioning the cancellation but rather keep telling me that it is being forwarded to a supervisor or to a different team but no-one actually processes the cancellation. I just keep getting a reference number. Now I see they have conveniently added the order/service to my bill even though it was never activated and even though I never ever took receipt of a router etc. This is really unacceptable that no-one is able to help me but have no issues taking my money for a service I am not using. I would never ever recommend Telkom to anyone and would never ever make use of nay of your services again which is why I have also requested my landline to be cancelled.
