Vodacom lost my Data or Sold me a Bogus Contract

Got sold a renewing of my contract via telephone that included 20BG of Data free, Great! I requested specifically if that 20GB would be available to me for the duration of my Contract term and not just for a month, they said yes absolutely for the whole duration of my contract (hence me going with this contract specifically)! Turns out it was only available to me for 1Month according to Lalucia Vodacom! 20GB of Data just disappeared when they did my Sim Swap...Now they tell me my contract only had the data available for 1Month! Either I got sold a bogus contract under false pretenses....or they failed to transfer my Data!!!
