Data woes

Last week Sunday I tried to purchase 2GB of data and I got an error message then I tried to purchase another 2GB after the 1st failed attempt. My amazement came when I got 2 messages to confirm both purchases were successful and this is not the first time this is happening. I immediately called the telkom call center to have one bundle returned and my money reversed but after 7 days I have not heard anything from telkom. Why is telkom such a bad company when it comes to customer care, you want us to fight you in everything. Please this is exhausting change your ways.
