Telkom Mobile Billing Department a Nightmare

Once again Telkom has not submitted the debit order for my Cellphone account -- this is now the 3rd time - please advise why this keeps happening and what must I do. Last month I paid and then you submitted a debit order as well but November and December no debit order was submitted and not again in February. This is very confusing if your billing department doesn't stick to the proper arrangements.<br> Why do they insist on a debit order and then dont submit and then send me a rude sms to state that my service will be suspended for non payment.<br> i prefer to pay myself then I know the payment is made on time but they insist on debit orders but then dont submit them.<br> I have sent 12 emails to different departments not one of them has been responded!! Disgusting
