Telkom consultant gave me a wrong package but they deducted and they are still billing me even though I cancelled on time.

Telkom network used give me problems with internet and will report every month until I decided to cancel the contract on February. At the cancellation department the guy who was supposed to cancel told me to try the Telkom infinite package cause it’s in partnership with Vodacom, he told if it also gives me problems I can cancel anytime. On March when the new package was supposed to kick in we realised on the 4th the TV is not play and our phones have no internet connection. I took the sim to check if there’s any data. On the phone the SIM card was working but when we put it back on the WiFi it didn’t work. I called Telkom they told me to take the WiFi router to the nearest Telkom shop along with the SIM card. When got to Telkom shop at Mams mall they realised that I given a wrong package, this package is for the phone only not for WiFi router. I was told to call them and person responsible for this to fix the issue, cause they can’t assist me since I took the product online over the phone. I called to give a feedback since they sent me to a Telkom shop. I then asked them to cancel the product with immediate effect, I was told they are going to cancel but I have to pay for the package I must try to put it on my phone and hotspot the TV and other devices. I did what the consultant asked me while she was still on the phone and it didn’t work, that package doesn’t hotspot it strictly work on one phone. But still even when I told the lady that the package is used she still didn’t terminate the contract with immediate effect me. I kept calling and complaining I don’t get assisted they take me from pillar to post. Last week when I called at the billing department they told me there was a usage therefore they can’t cancel the product,even though I explained the reason for that usage was during the time they were test the product to see if it’s working and again when they were check if it can hotspot. I even ask why now I’ve told about usage but earlier on when I cancelling when the was no usage they failed to cancel. Now that I want a dispute I am told about usage, I feel like it was all their plan when they telling to tell if the product is working and to try and hotspot the TV and other devices. I don’t want any thing to do with telkom anymore. I got angry and disputed my own money, they took it back and charged me R202 for doing that. They are quick to deduct and charge people but they can’t solve their customers issues.
