Breach of contract concluded

I had a contract with telkom for two (2) years, it also started very rocky with agents acting on behalf of telkom not being truthful and honest. Fortunately, one of telkom honest agents called and rectified. NOW, AN AGENT of Telkom called me again to renew the contract and i told him that this time i do not need the handset but only the minutes. He promised me that i will be paying only R198.00 for both simcards and will receive the following: Increase on the whatsapp data to 150, change the net data from 500 to 800 and give 25 minutes all network for both simcards/numbers. Currently the simcards are getting 150 whatsapp data, 25 min all networks, 150 minuets telkom to telkom. THAT IS NOT WHAT I AGREED TO. Which means this contract this is a breach of contract because it was made under false pretense. i agree to the contract because of the *good deal* that was promised to me but currently not delivered. I also cancelled the contract today the 08/03/2021 on the website because that is not i agreed upon with the agent who acted on behalf of telkom. My ID number ***
