5GB for R99 - 2 weeks no response from them

I app**** online in the beginning of the month. After only a week they called. I told the lady I am interested and she told me to hold on the phone for a minute. I held on for about 3 minutes and then cut the call as I was busy. When she called I told her that I am in class teaching and requested her to please call me back after 2pm when lessons are over. I am still waiting for more than a week and nothing yet......
