I am very Un happy with Vodacom

I am very Un happy with Vodacom. I went on LINE on Vadapay yesterday to buy a data bundle for some one else. I did pick there number from the phone book. But the bundle was send to me. I tried calling Vodacom but was just told it's a system error and there is nothing thy can do for me😭😭😭. Is have WiFi at home and at the office where am I supposed to use all that data? As I was still left wit 14G of my own? And next month it will expire and I will lose my money.
