Debit Order Shambles

On the 18th of December debit order for my mobile account went off my bank account. Great! Now the fun starts as the billing on their online service doesn't reflect that the payment was received. Start making calls only to be told that there is no problem as my payment shows on their side and all is well and the system will update to reflect payment. Now this morning I receive an sms to remind me that my debit order is due this evening!!!! Again a call to Telkom and again the same story that my account is paid up - so why the message? They say sorry, "they will escalate my call" but it won't happen today - its 7:30 am so why not today? I also tested their system - after my debit order had gone off I waited a couple of days and then made a small payment from their online payment portal - low and behold this amount has gone off and the amount they claim I owe for the month is the original amount less this payment... What a shambles - why have a debit order if they are not processing it!!! Am due for an upgrade but considering the reviews here on Hello Peter and my own experiences with Telkom I am going to go pre-paid
