Extremely disgusted!

I recently upgraded my Telkom modem device - Sept 2022. I had signed up to pay R135 for 20gig night and 20 gig day. I had stressed the importance of limiting this device to only R135 a month for the data agreed on. I did not wish to have an open line of any other "benefits" To my surprise Telkom invoices over the last 7/8 months have been inflated du to subscriptions being added on by users of the device. 1. My first enquiry was in December 22', to which I was advised a user accessing the wifi had subscribed to a gaming website. I asked the consultant to cancel all subscriptions as I did not wish for any further charges to inflate my invoice & debits on my contract. She had agreed this would be done and I need not worry about this again. (please bear in mind these calls are recorded) 2. I received another invoice for March/April 23', and yet again the billing had increased with the same reasoning. I yet again called Telkom, and was told it is my responsibility to ensure users of the wifi do not subscribe to gaming websites. I am still trying to understand how does one control that. The consultant very rudely advised it was "common sense." I went on to say to her that I had already called Telkom in Dec advising them that I did not want any further subscriptions inflating my invoice and this should have been cancelled in December 22' already. She said this can only be done for a specific period and if the user reactivates the subscription would be reactivated and continue inflating the invoice. I then wished to cancel this entirely. By then this call had disconnected. 3. I then had another agent call back a few hours later, I was not prepared to go through the whole process again so I said to her please cancel my contract, she agreed to assist and advised it will be cancelled. At this point I was NOT notified that there will be cancellation charges for the device, the remaining contract and the last months premium. By then this call had dropped and I expected the agent to call back, unfortunately no-one called back. 4. On Friday last week I called Telkom again, I spoke to a lady by the name of Thembekihle, I spoke to her at length about all the issues. She was supposed to do her enquiries on her end and revert to me before close of business on Friday. No phone call yet. Telkom is extremely difficult to get a hold off. Customers are being debited for things they have not enjoyed the benefit off and nobody bothers returning your call or explaining proper procedures. Extremely disgusted at the way they conduct business!
