Cell C billing

Cell C can you please explain!!! May debit order went off my account. Junes statement arrives with a charge of failed debit order amount. Junes bill being a total of May and Junes amount. I called 3 times to sort this out and was assured it was just an error on your Cell C app and that the systems had not updated - in this day and age??? Really!!!. Junes debit order you try to take the May and June (so May twice and failed debit order amount). Is this not theft? I called a Cell C branch who advised I come in with bank statements as proof. Bank statements provided and sent by Cell C branch to get a case number. Standing in the branch another customer says to me the same happened to her a couple of months ago! How many customers are you doing this to and how many have the time to sort it out. This is not right and should be made public. Will you refund me for the hours spent sorting this out as being self employed the time I take away is time I pay for!!!
