Telkom Accounts Department Useless

Hi,<br> <br> This is the seconds time Telkom sends me an SMS saying my account/service will be suspended because I have an amount due. Although they can't tell me for what I owe money. I have a set ADSL contract with them, and that amount gets debited ever month, but somehow they ad random R2000 that I need to pay or my line gets suspended. And no one at Telkom can tell me what this amount is for, just say that I need to pay it. <br> <br> How do I resolve this recurring issue ?<br>
