Incorrect billing

My complain has not been resolved regarding the incorrect billing while I have not used your services in August. You asked for my email address (***) but you wanted to pretend as if you were going to resolve this issue because it was on hellopeter but you are doing the same thing. I want justice to be done. You made me pay from 9 July R479 for unlimited 24/7 but by the 16 July I couldn't connect because there was no data. Checking online I discovered that I was allocated R250 package. From 16 July I couldn't use your services in August but in September you bill me R231.77. I want to know why. What happened to my R479 because it has not been refunded to my credit card if the R231.77 was for (9 July-16 July).
