Lost 70 G data bundle

In October 2018, I bought a 1-year valid 200 G data bundle for R1 999. This morning, 3 October 2019, the 70 G that I had left expired without any notification from Cell C. Had I been warned that the expiry date was coming up, I would have definitely opted for the data rol***** option. However, the expiry date of the data was not even shown on the report when dialling *101#. Upon visiting a Cell C store, I was told that since the data had already expired, there is nothing that can be done. My option to make use of the data rol***** was thus withheld from me. Personally, I feel that this is quite dishonest of Cell C since the new South African data law stipulates that data bundles has to have the option to be carried over beyond the expiry date.
