Overbilled 4 months in a row

Hi there, <br> I am a very disgruntled customer. I have been over billed for 4 months in a row now. <br> <br> Since June I have been billed for a 1Gig data bundle (Which I don't even receive) and HW fees for my phone from my previous contract. <br> This is unacceptable!<br> I need the 1 gig data bundle to be removed immediately from my invoice and future invoices as well as the HW fees. <br> Plus repayment for the last 4 months of overpaying. <br> If I paid you R300 short every month you would cut my contract. But now that I'm overpaying, nobody seems to be able to help me. <br> Please attend to this urgently. <br> <br> <br>
