be carefull of vodacom

in end october i got a call saying im a valued customer and i qualify for an upgrade. the more i told the lady im not interested as my contract is expiring end january 2024. she kept on saying its an sim only contract and i can cancel any time, she will send me the details and if im happy i must sign and sent back. needless i never signed as i wasnt interested, just wanting to cancel. this morning i phoned in to cancel just to find that they continued with the sim upgrade and if i want to cancel i must pay for early cancelation fees, and the consultant helping me was rude , saying she will forward everything, i need to pay before they cancel my contract then she just dropped the phone, havent received anything yet and why should i pay for something i dont want my contact nr ***
