my husband get me a cellphone on contract Well

No one explained or told me with this contract I get R100 airtime so what does everyone do they turn it into Data when I call customer service for help they tell me I can't. What the Hell I am so furious I would never have taken this pathetic contract then. Why don't you people tell this or explain this to customers I feel ******* and now I sit with a cellphone I can't even use I'm telling you now someone better call me before I take this even further...
