No way to pay - I've tried!!

I've had an ADSL line installed but no what I try I cannot pay Telkom.<br> <br> I don't know if the account number they've supp**** is wrong but I've tried adding them as a beneficiary on Standard bank as well as FNB but the recipient is rejected every time. Every month I receive an SMS saying I owe a sum, but they never answer their telephone lines even when I pretend to need a new service!!<br> <br> I've even linked my account on their website but then when i click on My Invoices, nothing appears, even though the Account Balance tab shows my outstanding balance! Argh! <br> <br> I do not want a bad credit record because Telkom doesn't have their account payment processes in order!
