Telkom is a useless company

Telkom has been the most unreliable services when it comes ti debit orders. Very quick to debit your account but can never refund you. I still have a case pending from Telkom which has not been resolved as yet. Last week the 30th i made an Eft payment so i dont fall in arrears. On the 31st i see telkom decided to put a tracker and debited my account after i had made payment. Surely by now the 05th of june payment should of reflected by now... I have been calling telkom this whole day and no luck 081180 im told its a problem with the lines. Fare enough. Why cant they responding on email or call me then..
