im so mad

i bought airtime of R25 on Sunday and yesterday i was only left with R26 then i bought data for R2.70 today when i wake up there's no data and no airtime when i call the customer service number I'm assisted by Ntombi who gives me attitude and tells me that whats app is the one that finished my data, then i decide its time i change my network provider to something better and that wont vanish my airtime. For anyone using cell c or who wants to join cell c i would advice never to even think of using it,
