Charging me for inclusive data

This is the email I sent to [Email Removed]<br> I've been having this issue now for three months.<br> ---<br> Today's date is 2015-08-26<br> My account was debited with an overcharged cell c amount.<br> <br> This relates to data contract with number ### (20 giga post paid package)<br> This contract offers 5gigabyte daytime and 15 gigabyte midnight data.<br> <br> Since I upgraded to this package (from May 2015), I have been incorrectly billed for inclusive midnight data. <br> This should be free and I should not have been charged for this.<br> To proof that this is midnight data, I looked at the invoices and can confirm that :<br> (1) I haven't exceeded my 15 gigabyte midnight data limit<br> (2) It was definitely within the midnight period.<br> <br> Attached is the invoices of May, June and July 2015.<br> For June 2015 especially I have been billed an extremely high R2000 on top of my supposed monthly subscription.<br> <br> I also attached my own spreadsheet that I used to investigate this.<br> <br> I tried blocking the debit order, but somehow your debit order has come through.<br> I feel like I am being ****** by Cell C now.<br> <br> I haven't had this kind of problem when I was on a 2 gigabyte package.<br> <br> To contact me, try these numbers:<br> #
