Pathetic Scandal!

I have been purchasing data from Cell C online and I have had an issue when payment is being made the data goes to a wrong number, the number it goes to is unknown to me. When I had this issue twice before I called them and they could not assist me as they said it was a fault of mine, But now I have loaded data and the same thing happened the number changed and I didn't receive the data, it seems like this is a **** of Cell C with the online customers. I am sure it is not a fault of mine as this time I was certain the number was correct! I want to be reimbursed as I have lost over R100 now on data!!!!!
