Vodacom 10meg. "uncapoed" Lte contract

I took out a contact with Vodacom for an uncapped 10meg Lte in December 2021. A week ago our internet stoped working so I went to the vodacom shop they tested my modem and said that is working fine they will sinc my Network..nothing happend still no internet so I phoned Vodacom customer care last night they told me that my internet has a limit on for 400gig a month after that it gets cut off? I went back to the vodacom shop today and they told me that the "uncapped" limitless contract is a top up account and there is a limit of 400gig on?? Nobody told me that there is a limit on when I took the contract? Nothing of limit on the contract I signed? My vodacom app also say limitless? I dont understand? Must I just accept it if it is someting I did not know about? They told me to manage my data useage? What is the use then for an uncapped contract if there is a limit on?? Is the contract still valid its cleary not what I wanted? I wanted an "uncapped" limitless internet?? Be carefull when you take out a contact with them read through every page...I have been with Vodacom for a long time, this never happend I am really unhappy about this😒
