Telkom agents processing cancellation without consent

I went to the telkom store in Clearwater mall and received excellent service with regards to cancelling products I have with Telkom. I queried a WiFi contract I have with telkom asking the person how much to cancel ,he advised me there is no cancellation fee as it’s a sim month to month contract , of which I requested to cancel. A few days later I received a call from 1 of Telkoms cancellation contact centre agents who then proceeded to the tell me something different. The agent advised me that there is a cancellation amount that I need to pay of which I argued based on the information received from the store. I was then told that I must go to the store again but when I asked her for assistance on this matter she decline to provide it. I did not accept the cancellation process to proceed based on the new information given but in the new month I now see that I have no WiFi meaning that I’m liable to pay the cancellation fee. I am highly upset that she processed something that I did not give consent to. I did not receive a new router all I received was a new sim therefore should Telkom debit me the cancellation fee I will go to the ombudsman and lay a complaint on processes being concluded without my consent.
