Telkom has been billing me for a contract that they should have cancelled over 6 months ago

I app**** for a Telkom phone contract online. Before receiving the device and sim, I called to ask for the contract to be changed- essentially a different device and the contract would be R50 more expensive. I was told that it would be handled internally, my bill adjusted, and my account debited for the difference. When the device was delivered it was of the initial contract. I called, told many stories, the phone was collected...waaaaited for my phone to be delivered- nothing for weeks. Eventually I went into a store to get a contract (because I really needed a phone). Then I told 'online Telkom' to cancel the contract altogether.

They have been working on the cancelation since July 2019! I have spoken to at least 2 people who are very willing to help but they also do not know what is the hold up, they are forever waiting for feedback. Other times I call in, nobody even knows of a pending cancellation- as if there is nothing on the system. I have to tell the story over and over each time I speak to an agent...beyond frustrating and tiring. Telkom happily keeps on billing me- they already owe me over R2000.

However, when the device was delivered it was still the Huawei P30. I alerted Telkom that the wrong device had been delivered. I was told the Huawei would need to be collected from me and the delivery of the iPhone would be processed.
