Useless Call Centre

My account was handed over because I missed one month payment. The payment was made and the account is rehabilitated, Telkom deducted my total due on the 23rd and my billing supposed to be deducted on the 1st monthly. I've got a message now telling me that there will be a debit on the 29th for the same amount debited on the 23rd. I contacted Telkom call Centre today and the lady (Ayanda) said the amount is not reflecting yet on her system and there's NOTHING that she can do to assist me... I think that's bull**** . I asked her to escalate the call to someone who can solve the problem and she said her team leader is busy on the phone... (I understand that's a call Centre) I was on hold for 24 minutes 57 seconds until they hang up. I think the lady is incompeted. I thought your Call Centre is there to resolve issues but now I think otherwise.. They are there to greet and confirm customers details. So if they can't help me , who's gona help me????
