Billed despite line not working

Good Afternoon,<br> <br> My telkom line has been out of service since the 28th of Decmber 2015, despite the fact that my line has not been working since than I have been billed since than. I have paid my account however I think I should be refunded the amounts paid for no service.<br> <br> Kindly have someone from your accounts department look into this matter urgently. The line has now been resorted today 14h00.
