SSDA / CellC

To CellC, Not sure what to do but SSDA just phoned me 3rd April time 1h55pm to tell me if I am aware that CellC handed me over on 9th Jan 2023. I did spoke to a CellC costumer care last week and the issues ( account paid Up ) is been sorted out. But now SSDA keeps phoning me to tell me I still own them R 1300 . This account was paid on 24th Jan 2023. I ask my self what is going On ?? This is now going on for 3 months .
