CellC has the worst client service ever

So I phoned in the beginning of Feb to make arrangements to change my debit order date and banking details as I will be in Korea for the next year but still want to make sure everything gets paid, so my salary date changed thats why I called them.The consultant informed me that it will be no problem to move it from 28Feb to 15th of every month,which means it should've gone off on 15 March from the new account..On 28 Feb they took the debit order from the new bank account and there was insufficient funds since my pay date changed.I phoned them again and they informed me that it has been changed to the 15th now. So yesterday I got a message that my phones will be cut off so I phoned for the 3rd time,asked to speak to a manager but she was TOO busy,so the 3rd consultant informed me that the debit order of the 28th of feb +- R1700 and then the debit order which was supposed to be 28th of March +-R1700 will now be deducted together on 15 March I mean where do they think money comes from,no one informed me about this previously when I called. I'm a loyal client,I don't expect royalty, just can't understand why they can't move the dates without doing dubbel debit orders???And now the debit order for both amounts was scheduled for 15March but I still get messages that my phone will be cut off today?how can my phone be cut off after you scheduled your dubbel debit order.But Thanks CellC your super great with your client care and assistance in special situations especially your managers who are too busy , I now after 5years understand why people complain about you.
