Using data after paying for whatsapp bundle

I have purchased a whatsapp bundle for the second time now. The first time I purchased it it seemed to work.<br> On the second purchase of the whatsapp bundle, data has been used for whatsapp usage after paying for the whatsapp bundle.<br> <br> Kindly note that when I have only been using whatsapp, my data is consumed. Other applications are turned off. Also, and more significantly, my cellphone data usage chart, shows that whatsapp is consuming data, even when background data for whatsapp has been turned off.<br> <br> I made a call during the week. I was first refused help after not knowing the date and value of my last purchase of airtime. After demanding to speak to a supervisor I was assisted following some more reasonable security questions. The operator dismissed my complaint, saying that the bundle was working as it should. But after observations I found that it was clearly not working.<br> <br> I called Cell C again. I explained the situation and was almost blown off again but was then told to hold that the technical department would assist. I was put on hold a couple of times and the technical department sent me instructions to set up my phone. But still I had no success.
