Not a _A|_valued customer_A|A

A few months ago I requested that Vodacon deducts my account on the 27th of each month because for me that is more convenient and I know for a fact that with this way they will always get their money and I can be stress free. Last month (September) I got a machine operator phoning me to make me aware that my account for the month is in arrears so again I requested for my account to be deducted on the 27th. I understand that if the date falls on a weekend it will be deducted after the weekend, so according to my understanding and what the lady told me a few months ago is that if the 27th falls on a Saturday it will be deducted on the 29th that is a Monday. So why did that not happen? 5 October 2015 my phone is cut off because Vodacom did not deduct for why I do not know. Why did no one phone, sms or email me to notify me of this matter and so that I can make arrangements? I am a female driving alone from Roodepoort to Rosabank and back every day and I need a phone so that I can contact someone when I am in an emergency. I feel that all these years being with Vodacon I am not a \valued customer"I prefer talking to a human and not a machine please """
