No explanation on Data and Airtime

I spoke to a Prudence and Lindi today about my data and airtime dissapearing over night and I was told that there is nothing they can do about hence there was no info on the system displaying a proper reason .<br> <br> I had 29megs and R7 airtime which dissapeared and was told I have promo data of which I did not buy . I bought 1 gig data on the 24 Feb of which I was told it also doesnt reflect and was left with 29meg from the 1 gig . I woke up this morning with only 4meg left and no airtime at all . I always leave my data hon everynight and has never had such a problem .<br> <br> I want answers as I was told there was no team leader on the floor to help me . I also want my data and airtime back on my phone as I'm afraid to load airtime again .
