Vodacom extending contract without permission

Vodacom contract – Vodacom online contacted me to say I never received the special with my previous upgrade, and they would like to add the 5GB data and modems to my two contract numbers. I repeated 3 times (Vodacom are more than welcome to listen to their recording they made) that this is not a new contract, and it was repeated 3 times “no sir, it is not”. Now my contract was supposedly due for an upgrade, but my contract has been extended to 2024 due false information given to me. When I contacted Vodacom through their branch, I was informed that I missed the cooling period of 14 days. I have not opened the modem boxes, as I do not need them, and Vodacom gave me false information regarding the “offer that was supposed to have been given to me with my previous upgrade”, only to find out 6 months down the line they extended my contract without my knowledge or permission – what cooling off period, Vodacom get real and catch a wake up! After 20 years and more, Vodacom will not see me again – be careful, Vodacom are ****mers!!
