Cell c migrations department

Hi my name is Nakita I've been offered with a month to month data only sim from cell c off 10 gig 5 day and 5 night the lady who offered me this package told me I could increase the data at anytime, so I called a few days after that wanting to increase the data as I'm working from home and using that data which I thought would be enough but unfortunately not... The consultant assisted me and told me I would be called back in 2 working days to increase my data as my query needs to be handed over to the migrations department after 2 days went by I called again they said my case is still running its been over a month now and I've called several times so far with no luck as they keep telling me they will get back to me its so frustrating because now I have to top up my data which is costing me alot of money these people are very helpful when offering these sales/packages but when you need help afterwards no one seems to care so I didn't have any other option of how to get help so Pls I need help
