TELKOM is a ****!!!!

My mother took a contract with telkom on the 26 January 2022 she took a laptop with data and was told by the sales advisor it's a 2 year contract. January 2024 we went to cancel the contract only to our surprise she had 1 more year and we were told to come back January 2025. We called telkom in November and they told us her contract ends in January 26 but her last payment will be in February, we got abit confused but they explained that because we will be using the data in January, her data will be billed in February but her laptop contract ends in January which made sense. We called again December and to our surprise they said our contract end on the 23rd of March, I called 3 times different days and different agents confirmed the 23rd March 2025 which is ridiculous because we have the invoice that states the contracts was taken on the 26th January!!! I called telkom yesterday and the agent said she will log a complaint and the reference will be sent to me by text, I waited and nothing was sent!! I called in today told the agent the whole story, she was so rude, she told me the system says my contract ends in March and that's that, I asked to speak to a manager and she told me even if I speak to someone above her it wouldn't make a difference coz the system says March!!! TELKOM IS A TERRIBLE COMPANY and some of their agents are terrible!!! I don't recommend telkom AT ALL!!! We have had enough!!! And it's very sad because my mother has been a loyal customer for years!!!
